Quick Answer: How Many Galaxies Are There In The Milky Way?

Can a planet have 3 suns?

An artist’s depiction of the view from a moon’s surface of a gas giant and three suns.

LTT 1445Ab orbits just one of the three stars, all of which are red dwarfs in the latter half of their lives, and the system is about 22.5 light-years away from Earth.


How fast is the Milky Way spinning?

130 miles per secondThe Milky Way, an average spiral galaxy, spins at a speed of 130 miles per second (210 km/sec) in our Sun’s neighborhood. New research has found that the most massive spiral galaxies spin faster than expected.

What is bigger than a galaxy?

Galaxies come in many sizes. The Milky Way is big, but some galaxies, like our Andromeda Galaxy neighbor, are much larger. The universe is all of the galaxies – billions of them! … Our Milky Way Galaxy is one among the billions of galaxies in our Universe.

How many stars are in a galaxy?

The Sun belongs to a galaxy called the Milky Way. Astronomers estimate there are about 100 thousand million stars in the Milky Way alone. Outside that, there are millions upon millions of other galaxies also!

Is the Milky Way moving?

The Milky Way does not sit still, but is constantly rotating. As such, the arms are moving through space. The sun and the solar system travel with them. The solar system travels at an average speed of 515,000 mph (828,000 km/h).

What are the 4 Suns?

Planets with four suns in their sky may be more common than previously thought, a new study suggests. Astronomers have spotted a fourth star in a planetary system called 30 Ari, bringing the number of known planet-harboring quadruple-sun systems to two. Numerous two- and three-star exoplanets have been identified.

How many galaxies are there in the universe?

The deeper we look into the cosmos, the more galaxies we see. One 2016 study estimated that the observable universe contains two trillion—or two million million—galaxies.

How fast is the Milky Way moving towards Andromeda?

402,000 kilometers per hourCurrently, Andromeda and the Milky Way are about 2.5 million light-years apart. Fueled by gravity, the two galaxies are hurtling toward one another at 402,000 kilometers per hour. But even at that speed, they won’t meet for another four billion years.

Are galaxies moving faster than light?

As dark energy causes the universe to expand ever-faster, it may spur some very distant galaxies to apparently move faster than the speed of light. … Over and over (and over and over) we’re told the supreme iron law of the universe: Nothing — absolutely nothing — can go faster than the speed of light. Done.

What are the closest galaxies to the Milky Way?

The Andromeda galaxy is the closest big galaxy to our Milky Way. At 2.5 million light-years, it’s the most distant thing you can see with the eye alone.

Are there 2 suns?

Imagine looking up and seeing more than one sun in the sky. Astronomers have done just that, announcing today (Sept. 22) that they have spotted a planet orbiting two stars instead of one, as previously thought, using the Hubble Space Telescope.

Which planet is closest to the sun?

MercuryZipping around the sun in only 88 days, Mercury is the closest planet to the sun, and it’s also the smallest, only a little bit larger than Earth’s moon.

Can we travel to another galaxy?

The technology required to travel between galaxies is far beyond humanity’s present capabilities, and currently only the subject of speculation, hypothesis, and science fiction. However, theoretically speaking, there is nothing to conclusively indicate that intergalactic travel is impossible.

What galaxy do we live in?

The Milky WayWe live in one of the arms of a large spiral galaxy called the Milky Way.

How many galaxies Does the Milky Way have?

Researchers dubbed this the eXtreme Deep Field. All in all, Hubble reveals an estimated 100 billion galaxies in the universe or so, but this number is likely to increase to about 200 billion as telescope technology in space improves, Livio told Space.com.
