At its nucleus the Milky Way Galaxy is about 100000 light-years wide and .?
The whole of the galaxy has a diameter of approx 100000 light-years, not just the nucleus! So it is not clear whether the question is about the galaxy or its nucleus.
What is the unit of measurement you use when dealing with traveling from galaxy to galaxy?
AU or Light year.When dealing with distances from one galaxy to the next, the AU or astronomical Unit and the light year are both used. The AU is the distance between the Earth and the sun or 93 million miles. The light year is how far light travels in one year, or 4.126 trillion miles.AU or Light Year.When ur talking about measuring something outside of our solar system then u would use Light years but when u r talking about inside our solar system then you would use AU's. Light years tells us how far light travels in a year. Light travels 150,000,000 km or 93,000,000 miles. AU measures the distance between the sun and earth which is 150 million miles or 93 million kilometers.
How large is the Universe in light years?
The distance that light travells in one year. Since light travels at 3000,000 km/sec, or 186,000 miles/sec, that's a very long way! The distance that light travells in one year. Since light travels at 3000,000 km/sec, or 186,000 miles/sec, that's a very long way!
What is the shape of Andromeda?
The Andromeda Galaxy is a spiral galaxy, just like our own galaxy (the Milky Way).The Andromeda Galaxy is a spiral galaxy, just like our own galaxy (the Milky Way).The Andromeda Galaxy is a spiral galaxy, just like our own galaxy (the Milky Way).The Andromeda Galaxy is a spiral galaxy, just like our own galaxy (the Milky Way).
What is the difference between physical distance and time distance?
The difference is magnitude, how long the distance is. Physical distance is measured in units like miles and kilometers, and are used for short distances. Time distance is measured in the distance light travels in a unit of time. The units are usually the kilometers light could travel in one year, and they are used for very long distances. Light travels 299,792.458 kilometers in one second. Then it must travel 60 times as far in one minute, 60 X 60 times as far in one hour, 60 X 60 X 24 in one day, and 60 X 60 X 24 X 365 in one year. In other words light travels 60 X 60 X 24 X 365 X 299,792.458 kilometers in one year. That is 9,454,354,955,000,000 kilometers. That number is so huge that it is much easier to say one light year. Alpha Centauri the nearest star to our solar system is approximately 4.22 light years away. Our galaxy the Milky Way is approximately 100,000 light years long. Using a distance measurement would be terribly cumbersome for interstellar distances or the distance between galaxies (intergalactic distances) which are even larger, so we use time distances.
How far away is earth from the Andromeda galaxy in kilometers in scientific notation?
The Great Galaxy in Andromeda (also known as the Andromeda Galaxy or M31) is about 2.5 million light years from Earth. When we look at this galaxy today, we see light that has been traveling through space for 2.5 million years; i.e. when we look at the Andromeda Galaxy, we are seeing it as it was about 2.5 million years ago! Think about this, we are looking back in time.1 light year is the distance that light travels in 1 year. Speed of light is 300,000 kilometers/second, find the distance that light travels from the Andromeda Galaxy to Earth in kilometers and express it in scientific notation.

What is the distance across the milky way galaxy?
Our Milky Way galaxy is 100,000 light years across.
How fast does Jupiter travel?
The orbital speed of Jupiter as it travels around the Sun is 13.07 kilometers per second. The average surface speed as it rotates is 12.6 kilometers per second.
How wide in kilometers is a galaxy whose width is described as 140 light years?
A light year is how far light travels, in a vacum, in one Julian calander year. This equals 9,460,730,472,580.8 km. So, a galaxy 140 light years wide would be...1,324,502,266,161,312 km wide.
Which galaxy is the Orion nebula in?
The Orion nebula is part of our own galaxy (the Milky Way). The Orion nebula is about 1500 light-years away from us. Our galaxy is about 100000 light-years across.
How far is the Andromeda galaxy from earth in kilometers?
The Andromeda Galaxy is about 24 000 000 000 000 000 000 km away from Earth.
How far does the galaxy travel in 1 year?
Assuming the galaxy in question is the Milky Way Galaxy.456,499,200 kilometers (283,655,452 miles)
What is the total size of the milky way galaxy?
It is a barred spiral galaxy with a diameter of 100000 to 180000 light years, and contains 100-400 billion stars.

How long would it take a light beam to go across a galaxy 50000 light years in diameter and return?
It would take 100000 years.
What two ways that earth moves?
It orbits around the sun and it travels with the sun around the centre of the Milky Way Galaxy.
