These are the 2 brightest stars in the sky. However Canopus is a lot more

luminous because it is much further away.

Canopus is about 310 light years away.

Sirius is only 8.6 light years away.

What are the 2 brightest stars in the sky and how can they be identified?

The two brightest stars in the sky are Sirius and Canopus. They can be identified by their brightness and position in the night sky. Sirius is the brightest star and can be found in the constellation Canis Major, while Canopus is the second brightest and can be found in the constellation Carina.


Is the north star brighter than Sirius?

No. Sirius is the brightest star in the night sky. Polaris is much farther down the list.


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.


Even though this star has an absolute magnitude greater than that of sirius it looks dimmer from earth since its 100 times farther away?

The star's absolute magnitude is a measure of its intrinsic brightness. Sirius appears brighter from Earth than a star with a greater absolute magnitude because Sirius is closer to us, which affects its apparent brightness. The star with the greater absolute magnitude might be intrinsically brighter but is much farther away, leading to its fainter appearance from Earth.


How much larger is capella than Sirius?

Capella is about 42.2 light-years away from Earth, while Sirius is about 8.6 light-years away. Therefore, Capella is approximately 4.9 times larger in terms of distance from Earth than Sirius.


Is it true that a stars absolute brightness is when its seen from earth?

No - a star as seen from earth is it's apparentbrightness. It's absolute brightness is measured by astronomical instruments. The brightest visible star from earth is Sirius, in the constellation Canis Major. Spica, in Virgo, has a much higher absolute brightness than Sirius, but Sirius is much closer to earth, so it is apparently brighter than Spica.

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.


Which star has the less absolute magnitude rigel or Sirius?

Sirius has a lower absolute magnitude than Rigel. Sirius is one of the brightest stars in the sky with an absolute magnitude of 1.42, while Rigel has an absolute magnitude of -8.1, making it much brighter than Sirius.
