Not only will I give you an example of a star but some others also.
TYPES OF STARS. The sun is a typical star but,not all stars are like the sun-they vary enormously in size,colour and temperature. Newly formed stars are extremely bright and hot bluish white stars to dim,cooler ones. The sun is a "middle aged "star,5 000 million years old. Over 50 per cent of known stars are binary and many stars vary in brightness,unlike the sun,whose light remains steady.
The colour of stars varies from an intense blue-white though yellow and orange to a dim red.
Spica is a bluish-white and it's surface temperature is 25000 degrees centigrade.
Sirius is white and it's surface temperature is 10,000 degrees centigrade.
The sun is yellow and it's surface temperature is 6,000 degrees centigrade.
Acturus is orange and it's surface temperature is 4,000 degrees centigrade.
Betelguse is red and it's surface temperature is 3,000 degrees centigrade.
Two examples of red giants are Antares and Betelguese.
Antares is a red giant about 400 million km in diameter. It's surface temperature is 3,200 c.
Betelguese is a red giant and is about 560 million km across.

The best example of a Star is the Sun.
The Sun is 93,000,000 miles on average from the Earth.
The next closest star is roughly 4 1/2 Light Years away
and located in the Andromeda Galaxy.

Go outside. Look up. There's a bright white circular object in the sky. Don't look at it directly, it can permanently harm your vision. It is what we call the "sun". It is a star. More properly it is a G2 class main sequence star approximately 4.5 Billion years old. It is 93,000,000 miles away from where you are standing. Although it looks small, it is very big. Very Very Big.

Look up in the sky during the day. That bright thing you'll see is a star called the "sun."

The big lightbulb in the sky is a star.
But they come in all shapes and sizes and colours, just like people.

I wasn't going to answer this until I saw zahbudars answer.
Dewd...... You -really- need to learn a bit about cosmology. The closest star( named Alpha Centauri) is about 4.5 LY away, but that's nowhere even -close- to being in the Andromeda Galaxy (which is about 2.5 million light years away)

Look at the night sky overhead, and the dots of light that twinkle are stars. Those that do not are usually planets.
