How far is Epsilon Eridani from Sirius?
If Epsilon Eridani actually exisits, I think the distance is 10.5 light years.
Sirius has a parallax of 0.377 arc seconds How far away is it from earth in arc seconds?
The distance from Earth to Sirius is the reciprocal of its parallax angle, so it would be 1 / 0.377 = 2.654 parsecs away.
What star has a greater magnitude a Rigel or Sirius?
Sirius, which means that Rigel is brighter.
What is the color of Sirius?
Sirius is actually a binary star system.Sirius A is a type A1V star so has a colour of Blue White -> BlueSirius B is a white dwarf.
How hot is Sirius?
Sirius is a binary star system with two main stars, Sirius A and Sirius B. Sirius A, the brighter and more massive star, has a surface temperature of around 9,940°C (17,964°F). Sirius B, the smaller and fainter star, has a surface temperature of about 25,200°C (45,332°F).
Is there a far away planet that orbits Sirius A?
Neither Sirius A nor Sirius B have any known planets.
How far apart are Sirius A and Sirius B?
Sirius is a binary star system Sirius A and Sirius B.The distance separating Sirius A from B varies between 8.1 and 31.5 AU. (See related question).
Is Sirius a cold star?
No. Sirius is far from a cold star. Sirius is actually a binary system about 8.6 light years away. Sirius A is a white main sequence star just over twice the size of the sun. Sirius B is a white dwarf stellar remnant of about 0.978 solar masses. The temperature of the two stars are far higher than that of our sun. The sun is about 5778 Kelvin, Sirius A is almost twice that at 9,940 K and Sirius B is many times that at 25,200 K.

Sirius is approximately 8.6 light years distant. It is normally the brightest star in the night sky
How far is Sirus from the Milky Way?
Sirius is within the Milky Way.
What star is the brigtest of all-stars the sun or the sirius star?
Neither. The Sun only appears bright because it is close. Sirius is far larger and brighter than our Sun. Our Sun is probably in the top 40% of all stars in the Milky Way, while Sirius is probably in the top 5%. But there are many other stars that are far brighter even that Sirius.
Is sirius bigger than 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.
How long does the orbit of sirius a and sirius b take?
The orbit of Sirius A and Sirius B takes about 50.1 years to complete one full revolution around their common center of mass. Sirius A is the brighter and more massive companion, while Sirius B is a white dwarf. Their elliptical orbit brings them as close as 8.2 astronomical units (AU) and as far apart as 31.5 AU over the course of their orbit.
Sirius is twice as far from earth as which star?
Probably one of the Alpha Centauri stars at about 4.3 light years.
How far is Epsilon Eridani from Sirius?
If Epsilon Eridani actually exisits, I think the distance is 10.5 light years.
Is 'Sirius C' real or not?
It is not real. Sirius is a two-star system containing only Sirius A and Sirius B.
