How large is VY Canis Majoris compared to?
VY Canis Majoris’s diameter is around 1.750 times greater than the sun’s at approximately 1.5 billion miles / 2.4 billion kilometers. If this hypergiant would be placed in the center of the solar system, its surface would extend beyond the orbit of Jupiter, and some estimate it would extend up to the orbit of Saturn.
Is VY Canis Majoris bigger than our solar system?
A: The biggest star size-wise is VY Canis Majoris, which is about 2,000 times wider than our sun. You can fit 9.3 billion of our suns into VY Canis Majoris. This star is about 4,900 light years from Earth and is found in the constellation Canis Major. This constellation represents one of the two dogs that follow Orion.
Is VY Canis Majoris the largest star?
Of all known stars, the VY Canis Majoris is the largest. This red Hypergiant star, found in the constellation Canis Major, is estimated to have a radius at least 1,800 that of the Sun’s. VY Canis Majoris a.k.a. VY CMa is about 4,900 light years from the Earth.
What is the diameter of Canis Majoris?
1.9758 billion km
VY Canis Majoris/Diameter
What is the 1st biggest star?
Answer: The largest known star (in terms of mass and brightness) is called the Pistol Star. It is believed to be 100 times as massive as our Sun, and 10,000,000 times as bright! In 1990, a star named the Pistol Star was known to lie at the center of the Pistol Nebula in the Milky Way Galaxy.
How many Earths can fit in the moon?
Size and Distance The Moon is an average of 238,855 miles (384,400 kilometers) away. That means 30 Earth-sized planets could fit in between Earth and the Moon.
How many Earths can you fit in Mars?
Mars is actually smaller than the Earth! The radius of Mars is 3,389.5 km, which is just over half that of the Earth’s: 6,371 km. If you assume they’re both perfect spheres, this means that you can actually fit about 7 Mars’s inside Earth!
Is Betelgeuse bigger than our sun?
Betelgeuse, a red supergiant star roughly 950 times as large as the Sun, is one of the largest stars known. For comparison, the diameter of Mars’s orbit around the Sun is 328 times the Sun’s diameter.
How big is the star VY Canis Majoris?
VY Canis Majoris is a pulsating variable star situated at around 3.900 light-years / 1.2 kiloparsecs away from the Sun. It has an apparent magnitude that varies from 6.5 to – 9.6, and its absolute magnitude is – 9.4. VY Canis Majoris is surrounded by a complex asymmetric circumstellar envelope caused by mass loss from the star itself.
What is the rotational velocity of VY Canis Majoris?
VY Canis Majoris has a rotational velocity of around 300 km / 186.4 mi per second. If a hypothetical object would travel around the star’s circumference at the speed of light, it would complete its journey in around 6 hours – in comparison to the sun, it would take it around 14.5 seconds.
Which is the largest star in the constellation of Canis Major?
VY Canis Majoris is an enormous supergiant or hypergiant located in the constellation of Canis Major. It is more than 1.000 times bigger than our sun, and it is among the largest known stars in the Milky Way galaxy. Key Facts & Summary
When was the VY Canis Majoris nebula discovered?
This nebula is so bright that it was discovered in 1917 with an 18 cm telescope, and also contains condensations that were once regarded as companion stars.
