Stars
Types of stars
Red Giant
a very large star of high luminosity and low surface temperature. Red giants are thought to be in a late stage of evolution when no hydrogen remains in the core to fuel nuclear fusion.
Supergiant
a very large star that is even brighter than a giant, often despite being relatively cool.
White Dwarf
a small very dense star that is typically the size of a planet. A white dwarf is formed when a low-mass star has exhausted all its central nuclear fuel and lost its outer layers as a planetary nebula.
Supernova
a star that suddenly increases greatly in brightness because of a catastrophic explosion that ejects most of its mass.
Neutron Star
a celestial object of very small radius (typically 30 km) and very high density, composed predominantly of closely packed neutrons. Neutron stars are thought to form by the gravitational collapse of the remnant of a massive star after a supernova explosion, provided that the star is insufficiently massive to produce a black hole.

Definitions
-
Star
A massive self-luminous celestial body of gas that shines by radiation derived from its internal energy sources
Solar System
A star system in which object orbit around a star (for us it's the star). This includes the 8 planets which orbit around the sun.
Planet
A celestial body that orbits a star, it is big enough to have gravity force it into a spherical shape and for gravity to clear any objects away near its orbit.
Galaxy
A system of million/billions of stars, with gas and dust, the system is held together by gravitational attraction
Temperature and colours

-
Blue
The hottest of the temps ranging from 10,000-50,000 K
We are essentially made up of stars, because the common elements found on stars can also be found in us.
