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]
What are facts about Canis Minor?
Canis Major means "great dog". It was discovered by Ptolemy. It contains Sirius, the dog star. Sirius is the brightest star in the sky (after the sun). It has a right ascension of 7h. It has a declination of -20 degrees. 4 of its stars have planets. The "dog days of summer" are so called because Canis Major was visible during the hottest time of the year. It was sometimes considered as Orion's hunting dog. There is also a Canis Minor.
