The average distance to the stars that make up the constellations in the night sky around the sun is about

26 light years away for stars which are a bit closer to the earth and several thousand light years away for distant stars

Explanation:

Due to the large distances of cosmological bodies from each other, these distances are measured in light years.

A light year is the distance light can travel in a year which is approximately equal to 9.46*10^{12}km.

The constellation refers to a cluster of stars which appears at night. viewing from earth,they appear close to each other. their distances apart are however very huge.

The distance of the stars closer in the constellation from the earth is about 26 light years away, which for more distant stars are a couple of thousands of light years away.

an ion is a charged atom or molecule. it is charged because the number of electrons do not equal the number of protons in the atom or molecule. an atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.
