How many solar systems are in our galaxy?

“The Short Answer: Our planetary system is the only one officially called “solar system,” but astronomers have discovered more than 3,200 other stars with planets orbiting them in our galaxy.”

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.”

What are the 7 solar systems?

“The planets, in order of their distance outward from the Sun, are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.”

What are the 12 solar system?

“The Latest. Our solar system consists of our star, the Sun, and everything bound to it by gravity – the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune; dwarf planets such as Pluto; dozens of moons; and millions of asteroids, comets, and meteoroids.”

What is beyond the universe?

“The trite answer is that both space and time were created at the big bang about 14 billion years ago, so there is nothing beyond the universe. However, much of the universe exists beyond the observable universe, which is maybe about 90 billion light years across.”

How many Earths are there?

“Out of those 40 billion Earth-like planets, how many other worlds might there be that support life? These same scientists have concluded that planets like Earth are relatively common throughout the Milky Way galaxy.”

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.”

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.”

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.”

What makes up 99% solar system?

“By far most of the solar system’s mass is in the Sun itself: somewhere between 99.8 and 99.9 percent. The rest is split between the planets and their satellites, and the comets and asteroids and the dust and gas surrounding our star.”

Is there a 10th planet?

“There is no known Planet X or 10th planet in our solar system. Scientists have been looking for about a hundred years. It was believed that such a planet was required to explain the orbital characteristics of the outer planets Uranus and Neptune.”

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.”

How big is the universe?

“While the spatial size of the entire universe is unknown, it is possible to measure the size of the observable universe, which is approximately 93 billion light-years in diameter at the present day.”

Is Smiley a planet?

“Measuring about 108–167 kilometres in diameter, it was discovered in 1992 by David C. Jewitt and Jane X. Luu at the Mauna Kea Observatory, Hawaii. After the discovery, they dubbed the object “Smiley” and it was shortly hailed as the tenth planet by the press.”

Who created the God?

“No one created God. God got created as the universe grew and changes. God is the cumulative energy of the universe. So, infact universe created God.”

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.”

Does the multiverse exist?

“Even though certain features of the universe seem to require the existence of a multiverse, nothing has been directly observed that suggests it actually exists. So far, the evidence supporting the idea of a multiverse is purely theoretical, and in some cases, philosophical.”

Can galaxies have 100 billion solar systems?

“Full Article. Our Milky Way galaxy contains a minimum of 100 billion planets according to a detailed statistical study based on the detection of three extrasolar planets by an observational technique called microlensing.”

Is there 11 planets in our solar system?

“Our solar system is made up of a star—the Sun—eight planets, 146 moons, a bunch of comets, asteroids and space rocks, ice, and several dwarf planets, such as Pluto. The eight planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Mercury is closest to the Sun.”

Do all galaxies have solar systems?

“Galaxies can take various shapes, from spiral to elliptical or irregular. Milky Way is a spiral galaxy. Galaxies are made of billions of stars as well as their solar systems. That means other stars, like the Sun, can have their own solar systems made up of hundreds of planets, all of which orbit around them.”

How many systems are in the Andromeda Galaxy?

“The Andromeda galaxy has 25 satellite dwarf galaxies and is estimated to contain more than trillion stars within its two spiral arms. Like many other elliptical galaxies we observed, it has a black hole with more than 100 million solar masses in its center.”
