Frequently Asked Questions
What Is The Brightest Star In The Night Sky?
The brightest star is Sirius, also known as the Dog Star. It is part of the Canis Major constellation. Sirius is roughly 8. 6 light-years away from Earth.
How Many Planets Are In Our Solar System?
Our solar system has eight planets. They include Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
What Is A Light-year?
A light-year is the distance light travels in one year. It’s about 5. 88 trillion miles or 9. 46 trillion kilometers.
