2012年1月31日 · Rigel is the most luminous star in our local region of the Milky Way. The star is so bright that if viewed from a distance of 1 Astronomical Unit (Earth's distance from the Sun), it would shine as an extremely bright ball with an angular diameter of 35° with magnitude -38.

5 天之前 · Rigel location is in the Milky Way, our Galaxy. Based on the spectral type (B8Ia), Rigel colour is blue, which means that the star is one of the hottest stars in the Universe, hotter than our star. Rigel is the brightest star in Orion and the 7th in the night sky based on the Hipparcos 2007 apparent magnitude. Rigel is a naked-eye star which ...

This tutorial will give you a better understanding of the size of the Milky Way Galaxy by investigating the distances to objects within the Galaxy and to other objects in the Universe. Below is a picture of a spiral galaxy. This is a picture of …

Rigel is one of the most noticeable stars in the winter sky. With an apparent magnitude of 0.12, it’s the brightest star in the Orion constellation and the seventh brightest in the night sky. Rigel’s distance is approximately 860 light-years away from Earth, but because of its brightness and size, it is easy to spot with the naked eye.

Size comparison between the two stars, Rigel and the Sun. Rigel is a blue super giant star who has finished his main streak, after consuming his hydrogen; it is located in the constellation of Orion. Rigel is expected to end his life as a Type II supernova, ending …
