How does the sun and its family roam around the milky way?
The Solar System is at a distance of about 25,000 light-years from the center of the Milky Way, and takes an estimated 200 million years to do one full revolution around the center of the Milky Way.
What is the distance that the Milky Way galaxy travels through space in one year?
The stellar disk of the Milky Way Galaxy is approximately 100,000 light-years (9×1017 km) (6×1017 mi) in diameter, and is considered to be, on average, about 1,000 light-years (9×1015 km) thick. It is estimated to contain at least 200 billion stars and possibly up to 400 billion.
How long does it take our solar system to Orbit the milky way?
Every 200 million years
What galaxy does planet earth belongs to?
Planet Earth belongs to the Milky Way galaxy, which is a spiral galaxy containing billions of stars, including our sun. The Milky Way is vast, spanning about 100,000 light-years in diameter. Earth is located in one of the galaxy's spiral arms, known as the Orion Arm or Local Spur.
What size is the galaxy compared to the moon?
The Sun is about 332,946 times more massive than the Earth. It is about 1,300,000 times the volume of Earth. As for the Sun and the Milky Way - The Milky way is composed of roughly 100 billion stars, so one can say that because the Sun is an average star, the Milky Way is, very roughly, 100 billion times more massive than the Sun. Another viewpoint: The latest best estimates have the Milky Way Galaxy containing about 500 billion stars. Using that number and a more accurate way of estimating the total mass of the stars gives: Total mass of our Galaxy is about 1.9 thousand billion times the mass of the Sun. Notice that's an estimate of the total mass of the Galaxy, including dust and gas. Then again there's "dark matter" of course, but let's keep it simple.
What is the Milky Way galaxey?
That's the galaxy in which we are located. It has a diameter of about 100,000 light-years, and an estimated 200-400 billion stars. We are something like 26,000 light-years from its center.
If a dwarf galaxy is 13.2 billion light-years from Earth and its apparent size is 0.000125 arcmin what would its diameter be?
500 light-years (200 times smaller than the Milky Way).
What is the COSMOS 786560 galaxy?
The COSMOS 786560 galaxy (one of the galaxies in the COSMOS survey) is a spiral galaxy 6000 million light-years (redshift of 0.66) from Earth in the Sextans constellation, and is 120,000 light-years in diameter (1.2 times larger than the Milky Way), and contains about 200 billion stars (200 percent of the Milky Way's stars).
What is the COSMOS 781155 galaxy?
The COSMOS 781155 galaxy (one of the galaxies in the COSMOS survey) is a spiral galaxy 7000 million light-years (redshift of 0.83) from Earth in the Sextans constellation, and is 120,000 light-years in diameter (1.2 times larger than the Milky Way), and contains about 200 billion stars (200 percent of the Milky Way's stars).
How big is the Milky Way Galaxy?
The milky way is approximately 100,000 light years across and 1,000 ly thick at the thickest part. 1 mile = 63,360 inches 1 ly = 9.461×1015 miles. So 1,000 ly = 9.461 x 1018 miles = 5.99x1023 inches thick. 100,000 ly = 9.461 x 1020 miles = 5.99x1025 inches across.
How long does it take for light to travel across the milky way?
Depends witch star it comes from. The closest stars light will only take 7 years but most of the stars (that are relatively closeby compared to the light of other galaxies) will take 200 or more.
What the diameter of the milky way in feet?
lets say the Milky Way galaxy is one hundred thousand lightyears 105 in diameter (several sources use this figure).A light year is 9,5 * 1015 meters which makes about 3.2 * 1016 feetSo the Milky Way is about 3.2 * 1021 feet across3 200 000 000 000 000 000 000
What is the ACS-GC 13043719 galaxy?
The ACS-GC 13043719 galaxy (one of the galaxies in the Extended Groth Strip survey) is an elliptical galaxy 3000 million light-years (redshift of 0.24) from Earth in the Bootes constellation, and is 100,000 light-years (same size as the Milky Way) in diameter, and contains about 200 billion stars (200 percent of the Milky Way's stars).
Where is planet earth in the milky way galaxy?
our galaxy contains between 200- to 400-billion stars arranged in a giant disc shape. The diameter is 100,000 light years with an average thickness of 10,000 light years. The Earth is located about 28,000 light years from the center of the Milky Way.
What is the Milky Way and how is it related to the solar system?
The Milky Way is a huge collection of somewhere between 200 and 400 billion stars, most of which are believed to have planets. Our Sun is one of those stars, and our Solar System is one of those billions of solar systems.The main part of the Milky Way has a diameter of about 100,000 light-years. This means it takes light 100,000 years to get across, from one end to the other.
What is the ACS-GC 13003331 galaxy?
The ACS-GC 13003331 galaxy (one of the galaxies in the Extended Groth Strip survey) is a spiral galaxy 7500 million light-years (redshift of 0.91) from Earth in the Bootes constellation, and is 120,000 light-years (1.2 times larger than the Milky Way) in diameter, and contains about 200 billion stars (200 percent of the Milky Way's stars). It emitted its light 7500 million years ago when the universe was 6300 million years old.
Is our local supercluster 50 million light years across?
The Virgo Supercluster (in which the Milky Way is located) is about 200 million light years across.
