Meet Alpha Centauri A ,Centauri B and Centauri C

Something Unique about Alpha Centauri is that it has three stars: Alpha Centauri A B, C (ABC)

Alpha Centauri A is the first and primary star. It is also slightly bigger than the sun being about 10% more massive than it. It is a white dwarf, but due to it's spectral type being G2 V it is more of a yellowish-white color.

Alpha Centauri B is slightly smaller than our sun. Even though it is a white dwarf, it has a much more orangish-yellowish color. This is because the spectral type of the star is K1 V.

Then there is Alpha Centauri C. It is the closest star from Earth. But that does not mean we could get there. It may be the closest, but it is still thousands and thousands of years away from Earth. It is referred to Proxima Centauri, but people call it Alpha Centauri as well. It is the smallest of the three Aplha Centauri. The other 2 are much bigger in size.

Formation of a Star

A star is formed when:

1. Gas and Dust collect

2. Gravity pulls in more gas

3. Core becomes very dense, hot and pressured so fusion begins

4. A star is Born!

Fusion: the process or result of joining 2 or more things together to form into a single entry.

A Planet?

Pluto, which used to be a planet not so long ago, is no longer considered one because qualify as a planet like Earth and Mars need three important things.

These include:

1.It needs to orbit the the sun-Yes, Pluto does orbit the Sun

2.It needs to has enough gravity to pull itself into a spherical shape-Yep, Pluto is spherical all right

3.It needs to have enough gravitational pull and govern all other objects in orbit-Sadly no it does not. Pluto is too small to govern everything around it. So in reality, it is a Dwarf Planet. The objects around Pluto have almost the same size as Pluto.

So, if Pluto is not a planet, then Alpha Centauri can't be one either. First of all, Alpha Centauri is a STAR so it can not be a PLANET. How could a star orbit another star. It can't. It's impossible. Alpha Centauri is a star and can't be anything else. It can be a body, but so can many other things in Space. No two bodies can be more then two things.

The size of Alpha Centauri is...?

Alpha Centauri has a diameter of 1,203,215 km. Thats pretty big, right? Well that is nothing compared to other stars in the universe. Alpha Centauri is the closest star system to the sun. It can fit into the sun 1.15606936416 times. It can fit into Earth 0.01056787856 times.
