What else can I help you with?
Is sirius moving away from or towards earth?
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.
Where is Sirius b located in the night sky?
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.
Is Sirius the largest star?
No. Sirius is the brightest star in Earth's night sky, but how bright a star appears is a product of its actual brightness and its distance from us. Sirius itself is actually two stars with Sirius A emitting the vast majority of the system's light. Sirius A is a fairly large star, but others are much larger.
Is Sirius closer to earth than Rigel?
Sirius is a star, not a planet, and it is not the closest star to Earth or anywhere near being the closest (technically the closest star to Earth is the sun, and the next closest is Proxima Centauri).
What is the orbit of sirius?
Sirius is a star therfore is doesnt orbit. Furthermore sirius is to distant for us to obtain such information.
What is the brightest star and its brightness?
That is Sirius. Its "apparent magnitude" is minus1.5 approximately. Sirius is the brightest star in the sky for us on Earth, but it's not the most luminous star in "absolute magnitude". The main reason that it is so bright is just that it is very close to us.
What makes Sirius the biggest star in the night?
Sirius is the brightest star in the night sky because of its proximity to Earth, at a distance of only 8.6 light-years. It is a hot, luminous star that appears bright due to its intrinsic brightness and close distance to us. Sirius is also a binary star system, with a smaller companion star (Sirius B) that adds to its overall brightness.
Why does Rigel not look as bright as Sirius?
Despite being more intrinsically luminous than Sirius, Rigel appears dimmer in the sky due to its greater distance from Earth compared to Sirius. The brightness of a star as seen from Earth is influenced by both its intrinsic luminosity and its distance from us.
Does the star Sirius or Betelgeuse have a greater parallax angle?
Sirius will have a greater angle, because it is closer to us.
What is the brightest star to us after the sun?
Sirius
Should the earth always had a greenhouse effect?
The earth has always had the greenhouse effect. It is what stops us from freezing so far away from the sun.
Does Sirius radio work anywhere in the US?
Yes Sirius radio works wherever satellite signal reaches.
