How Many Milky Way In Space

How Many Milky Way In Space. The milky way is about 1,000,000,000,000,000,000 km (about 100,000 light years or about 30 kpc) across. 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.

These estimates typically range from 100 billion to 400 billion stars. The galaxies aren't wandering, they're going somewhere; Astronomers estimate there are about 100 thousand million stars in the milky way alone.

Tell me more about galaxies. For a long time, astronomers were not sure how to answer this question.

Outside that, there are millions upon millions of other galaxies also! Hipparcos mapped millions of stars in our galaxy, but how many more are there?

Many of the milky way's stars, however, are tough to view. Our home galaxy, the milky way, contains at least 100 billion stars, and the observable universe contains at least 100 billion galaxies.

Scientists Believe The Universe Is Still Expanding Outward.

Recent estimates conclude that there aren’t only 100 billion galaxies in our universe, but rather, over 2. The universe is a vast expanse of space that contains all of everything in existence. The galaxies aren't wandering, they're going somewhere;

We Could Measure The Motion Of The Milky Way Relative To A Neighbor Galaxy, But This Galaxy Is Also Moving.

These estimates typically range from 100 billion to 400 billion stars. Other say that the mass of our galaxy is roughly 100 billion times the mass of the sun. There are different models for estimating the number of stars in the milky way and the answers they give differ depending on what is used as the average mass of a star.

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.

How massive is space?hard to understand all the figures etc. Our home galaxy, the milky way, contains at least 100 billion stars, and the observable universe contains at least 100 billion galaxies. Some sources say that the milky way consists of 100 billion stars.

It Is Very Difficult To Count The Number Of Stars In The Milky Way From Our Position Inside The Galaxy.

Astronomers estimate there are about 100 thousand million stars in the milky way alone. These stars form a large disk whose diameter is about 100,000 light years. But it wasn't until the 1920s that astronomers realized that the milky way is only one of many galaxies populating the universe.

However, Various Estimates Are Available:

A modern estimate vastly increases previous counts to as many as 2 trillion. That’s not the end of it; Our best estimates tell us that the milky way is made up of approximately 100 billion stars.
