How many planets contain a galaxy?

How many planets contain a galaxy?

“Doing the math, we can then say that the Milky Way galaxy has – on average – between 800 billion and 3.2 trillion planets, with some estimates placing that number as high a 8 trillion!”

How many planets are in each universe?

“Astronomers estimate that there are billions of worlds beyond our solar system. Astronomers estimate that there is roughly one exoplanet per star in our galaxy. Of course, some stars have many planets – our own Sun has eight.”

How big is our galaxy?

“Our galaxy probably contains 100 to 400 billion stars, and is about 100,000 light-years across. That sounds huge, and it is, at least until we start comparing it to other galaxies. Our neighboring Andromeda galaxy, for example, is some 220,000 light-years wide.”

How many suns are in our galaxy?

“There are likely to be many more planetary systems out there waiting to be discovered! Our Sun is just one of about 200 billion stars in our galaxy.”

Where is Earth in our galaxy?

“Earth is located in one of the spiral arms of the Milky Way (called the Orion Arm) which lies about two-thirds of the way out from the center of the Galaxy. Here we are part of the Solar System – a group of eight planets, as well as numerous comets and asteroids and dwarf planets which orbit the Sun.”

How many universes are in space?

“While estimates among different experts vary, an acceptable range is between 100 billion and 200 billion galaxies, said Mario Livio, an astrophysicist at the Space Telescope Science Institute in Baltimore, Maryland.”

How many universes are there?

“In a new study, Stanford physicists Andrei Linde and Vitaly Vanchurin have calculated the number of all possible universes, coming up with an answer of 10^10^16.”

What is bigger than universe?

“No, the universe contains all solar systems, and galaxies. Our Sun is just one star among the hundreds of billions of stars in our Milky Way Galaxy, and the universe is made up of all the galaxies – billions of them.”

What is the biggest galaxy?

“Earlier this year, astronomers found an absolute monster of a galaxy. Lurking some 3 billion light-years away, Alcyoneus is a giant radio galaxy reaching 5 megaparsecs into space. That’s 16.3 million light-years long, and it constitutes the largest known structure of galactic origin.”

What is our galaxy name in India?

“The milky way galaxy is known as the Akash Ganga due to its appearance.”

How heavy is the universe?

“Eddington gives the mass of the universe as 1022 stars averaging our sun in weight. Taking 2.0 × 1027 tons as the sun’s weight, then the mass of the universe would be 2.0 × 1049 tons.”

Is the galaxy bigger than the Sun?

“In May, other scientists announced that our galaxy is also slimmer than expected, a mere 700 billion times the mass of our sun.”

What’s the biggest star in the Milky Way?

“Milky Way”

“

Star name	Solar radii (Sun = 1)	Method
Theoretical limit of star size (Milky Way)	~1,500
RSGC1-F04	1,422	L/Teff
VY Canis Majoris	1,420±120	AD
KY Cygni	1,420±284–(2,850±570)	L/Teff

How many galaxies are in the universe?

“This tiny patch of sky was full of galaxies, almost 10,000, of all different sizes and shapes. By multiplying this number by the number of times this tiny patch of sky would fit into the entire sky, astronomers came up with an estimate of between about 100 and 200 billion galaxies.”

Do other galaxies have planets?

“Astronomers spotted what they believe may be the first known planet in another galaxy. More than 4,800 planets have been discovered orbiting stars other than our sun.”

Are there more than 8 planets in our galaxy?

“The eight planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Mercury is closest to the Sun. Neptune is the farthest. Planets, asteroids, and comets orbit our Sun.”

Is a galaxy bigger than a planet?

“From largest to smallest they are: Universe, galaxy, solar system, star, planet, moon and asteroid.”

Which is the biggest galaxy?

“Located almost a billion light-years away, IC 1101 is the single largest galaxy that has ever been found in the observable universe. Just how large is it? At its largest point, this galaxy extends about 2 million light-years from its core, and it has a mass of about 100 trillion stars.”

Are there dead galaxies?

“The Hubble Space Telescope has found not one or two, but as many as 6 galaxies that are dead, as far as their role of birthing stars is concerned. The Hubble Telescope was looking back in time to a period when the universe was some 3 billion years old.”

In which galaxy we live?

“Our Sun is one of at least 100 billion stars in the Milky Way, a spiral galaxy about 100,000 light-years across.”

Can a planet leave a galaxy?

“An extragalactic planet, also known as an extragalactic exoplanet or an extroplanet, is a star-bound planet or rogue planet located outside of the Milky Way Galaxy. Due to the immense distances to such worlds, they would be very hard to detect directly.”

What is our galaxy called?

“Astronomy > The Milky Way Galaxy. Did you know that our star, the Sun, is just one of hundreds of billions of stars swirling within an enormous cosmic place called the Milky Way Galaxy? The Milky Way is a huge collection of stars, dust and gas.”

Can all galaxies be seen from Earth?

“Answer: Yes, you can see a few other galaxies without using a telescope! Our nearest neighbors, the Large and Small Magellanic Clouds, are easy to see from the southern hemisphere. However, one of the most beautiful galaxies we can see with the naked eye is visible in the night sky all this month (November).”
