The measure of the distance between earth and the sun.

The closest star to the earth.

The most common star in the Milky Way.

Hypothetical stars that are theorized to be white dwarfs that have radiated away all their leftover heat and light.

A Neutron star that spins and gives off waves of radiation?

The speed of light.

The brightest star seen from from earth.

They are large, evolved stars that have largely exhausted its core but have not started thermonuclear fusion.

Stars that have blown off their outer layers late in their lives.

The polar opposite of a black hole, it ejects matter from its core into space.

The easiest constellation to see in the night sky.

Arcturus is this kind of star.

A star with a brightness between that of yellow stars like the Sun and red dwarfs. They are classified as stellar type K.

The mass of our sun.

This red super giant is the second-brightest star in the constellation of Orion.

These are the collapsed cores of massive stars that were compressed past the white dwarf stage during a supernova event.

Also commonly referred to as “failed stars”, they are sub-stellar objects that fill the gap between the most massive gas planets, and the least massive true stars.

Stars that orbit each other in a single solar system.

The temperature of the sun.

Big explosion on the sun.

This is a region of space having a gravitational field so intense that no matter or radiation can escape.

A star and is often referred to as a G-type main sequence star. A perfect example of this star would be the sun.

An object is formed when a neutron star collides with a star. Usually looks like a peanut.
