Solution
The correct option is C Red dwarf stars
- Red dwarf stars are the most common kind of stars in the Universe. These are main sequence stars but they have such low mass that they’re much cooler than stars like our Sun. The smallest red dwarfs are 0.075 times the mass of the Sun, and they can have a mass of up to half of the Sun.
- At 4.2 light years away Proxima Centauri is the nearest star to the sun. It is a very small red dwarf with a radius of around 97,000 km, which is around 14% the size of our sun.
