Stars

By Emma

Stars are very close to

earth the closest star to

earth is about 23.5 trillion

miles away. Stars are

also held together by

gravity. Initially stars are

formed by gas and dust.

How Far Away Are Stars From Earth?

• Stars are really far away. The closest star to earth is about 23.5 trillion miles away. The closest star to earth is the sun which is the source to most of the energy on earth.

What are Stars Made Of And Why Do We See Them At Night?

A star is a massive luminous ball held together by gravity. Stars are collapsing clouds of material composed primarily of hydrogen.

Stars are visible in the night sky, when they are not outshone by the sun. Stars are very hot and give off huge amounts of energy that form light and heat

Stars are formed initially from gas and dust. They are composed mainly of the hydrogen gas

Do Stars Ever Change Colour?

Stars are many colours and

sizes. The largest star is the

Red Supergiant Betelgeuse.

Next are the blue giants

Rigel and Polaris (the pole

star). Our sun called the

“Yellow Dwarf” that is a

small yellow dot.

Are Stars Hot? How?

Stars are giant nuclear

reactors, which makes

stars hot and bright. The

sun is getting hotter

which is adding heat to

the earth which is why

we have warming from

green house gases.

I researched stars because I really wanted to know why we see stars at night and not in the day. I also found out some other really interesting facts. Do you think there will still be stars in the next 150 years?
