They craped in the toilet and Looked up in the sky and said sh!t Sirius is moving away from earth.
Yes. Sirius actually consists of two stars. The main object, Sirius A is not only bigger than Earth but is almost twice the diameter of the sun. The secondary star, Sirius B is a collapsed remnant of a star called a white dwarf. It is slightly smaller than Earth but far denser.
Sirius, which consists of both Sirius A and Sirius B is in the constellation Canis Major, which, if you are looking south, appears below and to the left of Orion. Sirius B itself is too dim to be seen from Earth; the vast majority of the light from Sirius is from Sirius A. Even then, as a binary system, the two stars are too close together for us to see them separately.
Sirius does not orbit the Sun.
Sirius is a star, so it doesn't have an orbit like the planets do. Thus, you can't calculate a year for Sirius. All you can do is estimate its age in Earth years.
Sirius is the brightest star...Polaris is bigger then Sirius, Polaris is 360 to 820 light years away from earth, and Sirius is only 8.6 light years away. The Sirius star is known as the dog constalation, The polaris star is found at the tip and corner of the big dipper and the little dipper
A freaking telescope
Towards Earth, at 7.6 km/sec. They say that in the future, we might be in "Sirius" trouble - but the fact is that Sirius doesn't move exactly towards Earth; there is also a sideways movement, so Sirius would miss us.

Because in the sky it looks as if the sun is moving, but actually, the earth is moving but you can't feel it.
How close and far something is from you.
India astronomers recognized that the earth was a sphere.
Arab astronomers determined that the Earth is flat.
They can do so by examining the light from the star. Doppler shift can indicate this
No. There is no such thing as an "earth-like star" as Earth is a planet, not a star. Sirius A is a star that is larger and brighter than the sun.
Sirius is the brightest star in the night sky of earth not a galaxy
