Physical properties possessed by all stars: They are made of gases such as hydrogen and helium. They shine very brightly due to interaction of hydrogen and helium at appropriate pressure and temperature. They contain iron in their cores which monitors the fusion reaction.

These systems, especially when more distant, often appear to the unaided eye as a single point of light, and are then revealed as multiple by other means.

How do you classify stars?

Astronomers classify stars according to their physical characteristics. Characteristics used to classify stars include color, temperature, size, composition, and brightness. Stars vary in their chemical composition.

What is the biggest sun?

Is there a planet bigger than the sun?

To begin with planets, as that is the easiest question to answer, there are no planets bigger than the Sun or even close to the size of the Sun. At about 13 times the mass of Jupiter a planet becomes what is referred to as a “brown dwarf”.
