The biggest groups of stars are called galaxies. Galaxies can contain anywhere from a few million stars to many billions of stars. Every star you can see in the sky is part of the Milky Way Galaxy, the galaxy we live in.

What object contains billions of stars?

the Milky Way
Our galaxy, the Milky Way, is typical: it has hundreds of billions of stars, enough gas and dust to make billions more stars, and at least ten times as much dark matter as all the stars and gas put together.

What is the name of millions of stars?

The Milky Way is a huge collection of stars, dust and gas. It’s called a spiral galaxy because if you could view it from the top or bottom, it would look like a spinning pinwheel.

What galaxy contains millions of stars?

Stars are not scattered randomly through space, they are gathered together into vast groups known as galaxies. 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!

What is a group of stars called?

A constellation is a group of stars that appears to form a pattern or picture like Orion the Great Hunter, Leo the Lion, or Taurus the Bull. Constellations are easily recognizable patterns that help people orient themselves using the night sky. There are 88 “official” constellations.

Which star is the hottest color?

Blue stars
White stars are hotter than red and yellow. Blue stars are the hottest stars of all.

What is the largest star in the universe?

UY Scuti
The largest known star in the universe is UY Scuti, a hypergiant with a radius around 1,700 times larger than the sun.

What are the 4 types of galaxies?

In 1936, Hubble debuted a way to classify galaxies, grouping them into four main types: spiral galaxies, lenticular galaxies, elliptical galaxies, and irregular galaxies.

How old is our galaxy?

13.51 billion years
Milky Way/Age

Astronomers believe that our own Milky Way galaxy is approximately 13.6 billion years old. The newest galaxy we know of formed only about 500 million years ago.

How many galaxies are there?

One 2016 study estimated that the observable universe contains two trillion—or two million million—galaxies. Some of those distant systems are similar to our own Milky Way galaxy, while others are quite different.

Which is an example of a large collection of stars?

GALAXY – A large collection of stars, dust, and gas in space. A system of millions or billions of stars held together by gravity. Examples include our own Milky Way. BINARY STAR – A system of two stars, orbiting around on another.

Which is an example of a star system?

GALAXY – A large collection of stars, dust, and gas in space. A system of millions or billions of stars held together by gravity. Examples include our own Milky Way. BINARY STAR – A system of two stars, orbiting around on another. Binary (and other multiples) stars are very common.

Which is the largest group of stars in the night sky?

Note that the cluster is spherical and contains mostly red stars. Galaxies are the biggest groups of stars and can contain anywhere from a few million stars to many billions of stars. Every star that is visible in the night sky is part of the Milky Way Galaxy.

Which is larger a constellation or a star system?

Star Systems and Star Clusters Although constellations have stars that usually only appear to be close together, stars may be found in the same portion of space. Stars that are grouped closely together are called star systems. Larger groups of hundreds or thousands of stars are called star clusters. Star Systems
