How many planets are there in the 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! However, in order to determine just how many of them are habitable, we need to consider the number of exoplanets discovered so far for the sake of a sample analysis.

There are presently nine known planets in the solar system. It is possible that a tenth planet, referred to as “Planet X,” exists and is waiting to be discovered.

- In fact, the nearest Earth-like planet may be only 12 light years away, which is roughly 72 trillion miles. In all, about 8.8 billion stars in our galaxy have planets that are nearly the size of Earth and also have a surface temperature conducive to the development of life.here are likely 40 billion Earth-like planets in our Milky Way galaxy, astronomers say. This artist's rendition provided by NASA shows Kepler-69c, a super-Earth-size planet in the habitable zone of a star like our sun, located about 2,700 light-years from Earth in the constellation Cygnus.

Milky Way The Milky Way is a barred spiral galaxy that has a diameter usually considered to be about 100,000–120,000 light-years but may be 150,000–180,000 light-years. The Milky Way is estimated to contain 100–400 billion stars. There are likely at least 100 billion planets in the Milky Way. The Solar System is located within the disk, about 27,000 light-years from the Galactic Center, on the inner edge of one of the spiral-shaped concentrations of gas and dust called the Orion Arm.

How many stars are there in sky? Kornreich used a very rough estimate of 10 trillion galaxies in the universe. Multiplying that by the Milky Way's estimated 100 billion stars results in a large number indeed: 100 octillion stars, or 100,000,000,000,000,000,000,000,000,000 stars, or a 1 with 29 zeros after it.

How Many Stars Are in the Universe? Multiplying the number of galaxies — which is about 2 trillion — by the 100 million stars in the galaxy suggests there could be about 10 raised to the19th power stars in the universe, Conselice said. But this could easily be a factor of 10 higher, Conselice said. Jeanna Bryner contributed reporting to this article.

Billions of Earth-like planets in Milky Way: study In the Milky Way, about 1 in 5 stars that are like our sun in size, colour and age have planets that are roughly Earth's size and are in the habitable zone where life-crucial water can be liquid, according to intricate calculations based on four years of observations from NASA's now-crippled Kepler telescope.

The Sky May Be Filled with Earth-like Planets There are very roughly 200 billion stars in the Milky Way, so that gives us 20 billion stars. If one of every five has an Earth-like planet, that means there are about four billion Earth-like planets in our galaxy alone! And mind you, that’s only for stars like the Sun.

List of possible dwarf planets List of possible dwarf planets. It is estimated that there may be 200 dwarf planets in the Kuiper belt of the outer Solar System and possibly more than 10,000 in the region beyond. The International Astronomical Union (IAU) has accepted four: Pluto, Eris, Haumea, and Makemake, as well as Ceres in the inner Solar System.

How many stars are there in our Galaxy (Milky Way)?  (Intermediate) So, even though we cannot actually count the number of stars in the galaxy, we can estimate the number of stars in the galaxy as roughly 100 billion (100,000,000,000). It turns out that there are many more stars with mass less than the mass of the Sun than with mass more than the mass of the Sun. So, it all works out right.

- And just for fun, let’s see how many of all the planets in the Solar System fit into Jupiter: Saturn — 1.73, or 1 whole Saturn; Uranus — 20.94, or 15 with sphere packing; Neptune — 22.89, or 16 with sphere packing; Earth — 1,322, or 978 with sphere packing; Venus — 1,542, or 1,141 with sphere packing; Mars — 8,775, or 6,493 with sphere packing

How many stars are there in our Galaxy (Milky Way)?  (Intermediate) I am confused about the number of stars in our Milky Way galaxy. Some sources say that the Milky Way consists of 100 billion stars.Other say that the MASS of our galaxy is roughly 100 billion times the mass of the Sun.So because most of the galaxy mass is in the interstellar gaseous and dust nebulae there must be less than a 100 billion stars in it or the total mass must be greater.ther say that the MASS of our galaxy is roughly 100 billion times the mass of the Sun.

How Many Planets are in the Solar System? For those of us who believe dwarf planets should be counted as a subclass of planets, the latest status is that our solar system now has 13 planets: four terrestrial planets, four jovian planets, and five dwarf planets.

How many planets are there in the galaxy? What is even more astounding is the notion that the majority of these stars have their own system of planets. For some time, astronomers have believed this to be the case, and ongoing research appears to confirm it. And this naturally raises the question, just how many planets are out there? In our galaxy alone, surely, there must be billions! Number of Planets per Star:

- 100 Billion. About 20 percent of more than 100 billion stars in the Milky Way galaxy are bodies like the sun. About 22 percent of those sun-like stars are orbited by planets similar in size to Earth and in the so-called habitable zone, making them not too hot nor too cold to support life, according to the study released yesterday.

How Many Stars Are In The Universe? Some estimates peg the Milky Way's star mass as having 100 billion solar masses, or 100 billion times the mass of the sun. Averaging out the types of stars within our galaxy, this would produce an answer of about 100 billion stars in the galaxy. This is subject to change, however, depending on how many stars are bigger and smaller than our own sun. Also, other estimates say the Milky Way could have 200 billion stars or more. The number of galaxies is an astonishing number, however, as shown by some imaging experiments performed by the Hubble Space Telescope.

How Many Planets are in the Solar System? There are 12 planets in the solar system–Mercury, Venus, Earth, Mars, Ceres, Jupiter, Saturn, Uranus, Neptune, Pluto, MakeMake, and Eris.he more we discover about our Universe, the more we realize just how strange and wonderful it is. When Pluto was discovered 80 years ago, we never could have expected the variety of objects in the Solar System. Categorizing Pluto as a dwarf planet helps us better describe our celestial home.

Our Solar System Introduction A solar system is a star and all of the objects that travel around it—planets, moons, asteroids, comets and meteoroids. Most stars host their own planets, so there are likely tens of billions of other solar systems in the Milky Way galaxy alone. Solar systems can also have more than one star. These are called binary star systems if there are two stars, or multi-star systems if there are three or more stars. The solar system we call home is located in an outer spiral arm of the vast Milky Way galaxy. It consists of the Sun (our star) and everything that orbits around it. This includes the eight planets and their natural satellites (such as our moon), dwarf planets and their satellites, as well as asteroids, comets and countless particles of smaller debris.

How many solar systems are in our galaxy? For many years scientists have studied our own solar system. But until the last few years, we knew of no other solar systems. This may seem surprising, as the Sun is one of about 200 billion stars (or perhaps more) just in the Milky Way galaxy alone. With all those other stars, why haven't scientists studied other solar systems, at least enough to know how many are in our galaxy? Using regular visible light telescopes, planets are very hard to see in the glare of a star.

The Solar System Our Solar System is an amazing place. Not only is it home to eight planets, it also hold several dwarf planets, hundreds of moons, and thousands of stars and asteroids. The eight planets in our Solar System are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. These planets orbit the Sun.

How Many Stars Are In the Universe? Our particular galaxy is known as the Milky Way. Scientists estimate that there are 200 billion to 400 billion — yes, that's billion with a “b — stars in the Milky Way galaxy. The Sun is just one of those 200 billion to 400 billion stars. If that blows your mind, just wait! Our Milky Way galaxy is just one of the many galaxies in our universe.
