Why did the crow and the ravens go to the spring?

According to Greek legend, Apollo needed water in order to perform a ritual sacrifice, and so sent a crow or raven equipped with a cup to a nearby spring. During its journey, however, the bird proceeded to gorge itself on the fruit of a fig tree, and as an excuse for its tardiness brought back a water snake which it blamed for blocking access to the spring. Seeing through its lies, Apollo flung the crow, cup, and snake into the sky, which then became the constellations of Crater (cup), Corus (crow), and Hydra (water snake). Apollo also condemned the crow to eternal thirst, and the bird has had a distintive dry sounding caw ever since.

How far is Theta Crateris from Earth?

Using the original Hipparcos data that was released in 1997, the parallax to the star was given as 10.70000 which gave the calculated distance to Theta Crateris as 304.83 light years away from Earth or 93.46 parsecs. If you want that in miles, it is about 1,791,981,372,507,559.84, based on 1 Ly = 5,878,625,373,183.61 miles.

What is the temperature of the star Theta Crateris?

Based on the star’s spectral type of B9 V , Theta Crateris’s colour and type is blue main sequence star. Based on the spectral type, we can deduce that the surface temperature of the star is in the order of between 10,000 and 25,000K based on the notes from Harvard University. To put this in context, the temperature of our Sun is about 5,778 Kelvin as said by Google.

How to determine the location of a star in the night sky?

The location of the main sequence star in the night sky is determined by the Right Ascension (R.A.) and Declination (Dec.), these are equivalent to the Longitude and Latitude on the Earth. The Right Ascension is how far expressed in time (hh:mm:ss) the star is along the celestial equator. If the R.A. is positive then its eastwards. The Declination is how far north or south the object is compared to the celestial equator and is expressed in degrees. For Theta Crateris, the location is 11h 36m 40.95 and -09° 48` 08.1 .

What is the radial velocity of a star?

The Radial Velocity, that is the speed at which the star is moving away/towards the Sun is 1.00000 km/s with an error of about 4.20 km/s . When the value is negative then the star and the Sun are getting closer to one another, likewise, a positive number means that two stars are moving away. Its nothing to fear as the stars are so far apart, they won’t collide in our life-time, if ever.
