Gemini also includes a star object known as Messier 35 or M35. The Messier objects are a set of 110 astronomical objects first cataloged in 1771 by French astronomer Charles Messier.

What is the meaning of Gemini?

Gemini is Latin for "twins," although the twins identified with the constellation depend on the culture, according to Encyclopedia Britannica. In Egyptian astrology, the constellation was identified with twin goats, while Arabian astrology said it was twin peacocks. The Western world tends to identify these twins as Castor and Pollux from Greek myth. But other twin pairs identified with Gemini in the Western world include the older and younger Horus and the mythical founders of Rome, Romulus and Remus.

How far away is the constellation of Pollux?

(A light-year is the distance that light travels in a year, which is about 6 trillion miles, or 9.6 trillion kilometers.) Pollux has at least one massive planet orbiting it, while Castor has two companion stars.

What does the M35 look like?

M35 is just barely visible to the naked eye under a dark sky free from light pollution, and in low-power binoculars, this object looks like a cloud with bright stars in it, according to Space.com skywatching columnist Joe Rao.

Why are Geminids shedding?

The Geminids are associated with a weird near-Earth asteroid called 3200 Phaethon, which is shedding particles likely because of a collision in its ancient past. As Earth runs into these particles in its yearly orbit around the sun, some of the rock bits fall into our atmosphere and produce spectacular meteor trails.

How far away is Pollux from Earth?

Pollux, a red giant star, is 33 light-years from Earth, according to NASA, while Castor is about 51 light-years away from us. (A light-year is the distance that light travels in a year, which is about 6 trillion miles, or 9.6 trillion kilometers.)

What constellations are in the night sky?

Winter constellations are the constellations that are best observed in the evening night sky from late December to late March in the northern hemisphere and from late June to late September in the southern hemisphere. The most prominent northern winter constellations are Auriga, Canis Major, Canis Minor, Carina, Eridanus, Gemini, Monoceros, …

What are the two major asterisms that dominate the night sky?

Southern winter constellations are the same as northern summer constellations. There are two major asterisms dominating the winter night sky: the Winter Triangle and the Winter Hexagon. The bright stars Sirius in Canis Major and Procyon in Canis Minor are part of both. The Winter Triangle is formed by these two stars with Betelgeuse in Orion, …

What is the name of the asterism in the constellation Orion?

The constellation Orion itself contains several prominent asterisms: the hourglass-shaped asterism representing the body of the Hunter, the famous Orion’s Belt and Orion’s Sword. The constellation’s brightest stars, Rigel and Betelgeuse, are among the ten brightest stars in the sky. They are both supergiants and among the most distant first …

How many stars are in the Winter Triangle?

The Winter Triangle is formed by these two stars with Betelgeuse in Orion, and the Winter Hexagon is formed by a total of seven stars: Sirius, Procyon, Castor and Pollux in Gemini, Capella in Auriga, Aldebaran in Taurus and Rigel in Orion.

Where is the constellation Gemini?

The constellation Gemini can be found east of Taurus, between Procyon and the bright stars of Auriga. The constellation’s brightest stars, Pollux and Castor, appear similar to the unaided eye, but are really quite different.

Which constellation is the second brightest star in the sky?

Carina , a southern constellation that cannot be seen from latitudes north of 20°N, harbours the second brightest star in the sky. Canopus has an apparent magnitude of -0.74 and lies at a distance of 310 light years from Earth. The bright giant is circumpolar for observers south of latitude 37°S.

Where is Sirius located?

Sirius, the Dog Star, is the single brightest of all stars. Located in Canis Major , only 8.6 light years from Earth, Sirius is also the fifth closest star system to our own. It is a binary star system composed of an A-class main sequence star and a D-type white dwarf.

What is the name of the star that is visible with the naked eye?

Besides all this, Orion is home to a stellar nursery, a diffuse cloud of dust and gas, the famous Orion nebula, which is visible with the naked eye. Seen as the middle star in his sword, it appears as a fuzzy star with the naked eye, but with binoculars or a small telescope, you’ll see it as a nebula, a cluster of stars.

Which constellation is the closest to the Milky Way?

Andromeda, named after the princess of Aethiopia, chained as a sacrifice to the gods, and saved by Perseus, is one of the largest constellations of the winter sky. The constellation is best known for its most prominent deep-sky object, the Andromeda Galaxy, the closest spiral galaxy to the Milky Way.

What is the difference between the northern hemisphere and the northern hemisphere?

The actual difference is that in the northern hemisphere , more bright stars are visible in the winter sky , which also accounts for more star groups or constellations. Identifying the constellations is one of the most fun elements of exploring the night skies from our backyards.

What is the canopy of stars?

Identifying the constellations is one of the most fun elements of exploring the night skies from our backyards. The canopy of stars is like a celestial map, with constellations offering points of interest where we can stop to explore . Named after mythological creatures, they also connect us to ancient people who lived on earth before us and saw the same stars and same constellations, and eventually named them.

Why do stars shine brighter in winter?

But the difference in clarity is not the reason for this; in fact, according to scientific measurements, there is no difference in the clarity of the night skies in the winter and any other cloudless night of the year. The actual difference is that in the northern hemisphere, more bright stars are visible in the winter sky, which also accounts for more star groups or constellations.

Where to find Taurus the bull?

Using Orion’s belt as a reference, you can easily find Taurus the bull; if you extend an imaginary line from the hunter’s belt to the right, it points to Aldebaran, the bull’s red eye.

Which star is the easiest to find?

Orion is a winter favorite not only because it’s the easiest to find and recognize, but for two of its brightest, non-belt stars. Betelgeuse is one of the largest stars known to us, a red supergiant, and Rigel is a cooler blue supergiant.

How far away is Castor from Pollux?

Castor, which is farther than Pollux at 51 light-years away, has some interesting credentials as well. In fact, the point of light we see with the unaided eye as a single star, is in reality six stars. In a telescope we can see two, Castor A and B.

What constellation is Gemini?

Gemini is conventionally referred to as a winter constellation, yet such seasonal designations are rather loose. They simply tell the season when a star pattern is best …

How far apart are the stars in the sky?

They are just 5 degrees apart, making for a very good celestial yardstick in the sky. At New York’s Hayden Planetarium, there was a very popular lecturer in the 1940s and ’50s named Henry Neely who would point to Pollux and Castor and then down to a third bright star named Alhena, which marks one of Gemini’s feet.

Where can I find Gemini’s feet?

On moonless nights or in those places free of significant light pollution, stargazers can locate Gemini’s feet in the Milky Way. Its brightest stars, Pollux (yellow-orange) and Castor (bluish-white) mark the heads of the Twins. They are just 5 degrees apart, making for a very good celestial yardstick in the sky. At New York’s Hayden Planetarium, there was a very popular lecturer in the 1940s and ’50s named Henry Neely who would point to Pollux and Castor and then down to a third bright star named Alhena, which marks one of Gemini’s feet. Connecting these three stars, Neely would make reference to the "Wedge of Gemini," a far easier pattern for stargazers of today to find. "Somehow or other," Neely would tell his audience, "The ancient stargazers managed to find in these stars the outlines of two heroes standing close together."

What is Gemini’s time square?

Up until 1988, the summer solstice occurred within Gemini’s boundaries when the sun passed near the star Eta Geminorum on June 21 (the solstice point has since shifted west into the constellation of Taurus). Not far from Eta, Sir William Herschel discovered the planet Uranus — and in 1930, right next to the star Delta Geminorum, a tiny speck of light was identified as Pluto (once the ninth planet, now classified as a dwarf planet). The best meteor display of the year — the Geminids — appear to radiate from this part of the sky in mid-December and finally, Gemini is home to M35, considered to be one of the most beautiful star clusters. Dimly visible to the eye under favorable conditions, a good telescope shows it as a striking pattern of stars forming curves and festoons.

How far away is Pollux from the Sun?

Pollux is approximately 34 light-years away. It is estimated to be nine times bigger than our sun and is about twice as massive. In 1993, it was suspected that a planet was revolving around Pollux — that supposed planet was confirmed in 2006. It is a giant world, calculated to have a mass that is 2.3 times that of Jupiter and orbits Pollux with a period of 590 days. Originally designated as "Pollux b," the International Astronomical Union has formally christened this planet "Thestias."

What are the two stars that can be seen in a telescope?

In a telescope we can see two, Castor A and B. Furthermore, both A and B are themselves doubles, though much too close to be separated optically. Finally, well off to the south of the main pair is Castor C, a pair of dim red stars.
