How far is 10 Lacertae from Earth?

Using the original Hipparcos data that was released in 1997, the parallax to the star was given as 3.08000 which gave the calculated distance to 10 Lacertae as 1058.97 light years away from Earth or 324.68 parsecs. If you want that in miles, it is about 6,225,287,911,440,247.48, based on 1 Ly = 5,878,625,373,183.61 miles.

How big is the radius of 10 Lacertae?

10 Lacertae estimated radius has been calculated as being 3.70 times bigger than the Sun. The Sun’s radius is 695,800km, therefore the star’s radius is an estimated 2,575,548.22.km. If you need the diameter of the star, you just need to multiple the radius by 2. However with the 2007 release of updated Hipparcos files, the radius is now calculated at being round 6.03. The figure is derived at by using the formula from SDSS rather than peer reviewed papers. It has been known to produce widely incorrect figures.
