Procyon (Alpha Canis Minoris) is approximately 11.4 light years from us.
Alpha radiation does not have a colour. In order for something to have a colour, it must emit rays of visible light. Alpha radiation and light are two different things which have little to do with each other.
Alpha Centauri (the brightest star in the constellation Centaurus) is the closest star to earth, and is actually a double star system - when it's small companion star is on "our side" of Alpha C, it is actually closest. The system is about 4.3 light years away. Sirius is the brightest star in the night sky, a white giant, and is about 9 light years away.
4.3 light years===========================Sorry. "Light year" is an answer to "how far", not "how long".Alpha Centauri is about 4.4 light years away from our solar system and everything in it,which means that it takes AC's light about 4.3 years to get here.
All of them - alpha - beta - neutron - visible light - are examples of nuclear radiation.

VY Canis Majoris is about 4,900 light years from earth.
nope
Beta Canis Minoris (Gomeisa) is a star in the constellation of Canis Minor. It is approximately 170 light years from Earth.
That would be "Alpha Centauri". The distance is about 4.4 light-years.
The distance has been generally presented in Light-years, which is the distance light travels in one-year. The distance to Alpha Centari is 4.7 light-years (alpha Centari is 4.3 light-years distance).
