What color are the brightest stars in the night sky?
The 20 brightest stars in the night sky cover the range of star colors: Red, yellow white and blue-white. The single brightest star is Sirius, which is blue-white. Antares and Betelgeuse, both in the top ten, are very red stars, to the naked eye. And so on.
What is the size of the betelgeuse?
Betelgeuse boasts the diameter greater than the orbit of Jupiter. It has a mass of around 20 times the mass of the Sun, and its luminosity is almost 200,000 times greater than the Sun. So really, it is one of the biggest and brightest stars ever observed.
What special features is found in Orion constellation?
It is made of 20 stars, the bigest star is called Betelgeuse, the brightest star is Rigel (which is 40,000 times brighter than our sun; 7th brightest star in the sky) and it is in the shape of a warior. It also contains the Orion Nebula and the Horsehead nebula.
How big is Beetlejuice compared to the sun?
Betelgeuse (also known as alpha ori) is a very large star, an M supergiant. This is because it has evolved far from the state in which stars spend most of their lives, known as the main sequence. For stars on the main sequence, which includes our Sun, there is simple proportionality between size and mass, and also a simple scaling for luminosity. For evolved stars the situation is less simple. Betelgeuse is more than 1000 times larger than the Sun, and 50000 times as luminous, but only about 20 times as massive. Most of the light from Betelgeuse comes out in the infrared, however, which is very different from the Sun. One consequence of the advanced evolutionary state of Betelgeuse is that it probably was much more massive when it was on the main sequence, and has already lost a significant fraction of its mass (probably more than half) in a stellar wind.
What are the names of the stars in the pleiades?
Although it is often referred to as the Seven Sisters or Matariki, there are in fact thousands of stars in the Pleiades. The nine brightest stars of the Pleiades are named after the Seven Sisters of Greek mythology: Sterope, Merope, Electra, Maia, Taygete, Celaeno and Alcyone, along with their parents Atlas and Pleione.

How much does betelgeuse weigh?
It's around 20 times heavier than our Sun.
What is Betelgeuse?
The star Betelgeuse (or "beetlejuice") is a Type M red supergiant in the constellation Orion. It is pronounced "bet- L (like the letter L) -geese," meaning armpit of the giant. It is very luminous, and one of the largest stars known [See Link]. For comparison, if the star was at the centre of our solar system its surface would extend out between the orbits of Mars and Jupiter, engulfing Mercury, Venus, Earth and Mars. It has a mass 20 times that of our Sun (Sun = 1.9891 × 1030kg = 333,000 times that of Earth) It's approximately 600 light years from us. The name is a corruption of an Arabic word meaning "hand of the central one". It is likely that Betelgeuse will become a supernova. Because of its size and age of 8.5 million years it may explode within the next thousand years. (However, due to its distance from us, it may have already happened!!!) [It's also a name of a film]
