There is also a section that helps beginners choose and understand telescopes which are essential optical tools for all astronomers. You will also find out how to spot man-made satellites orbiting earth. If you are further interested, you could also find out how the physics of gravity and acceleration govern the celestial bodies in this solar system.

Also, you can find out your weight on any planet in this solar system!

Just click the picture of the planets on the top frame and it'll take you on the journey through the solar system and prepare you for your discoveries in astronomy!

What is astronomy?

Astronomy is the study of the matter in outer space, especially the positions, dimensions, distribution, motion, composition, energy, and evolution of celestial bodies and phenomena. More than that, Astronomy is a fun hobby in which many enthusiasts just enjoy looking up at the sky! For many "astronomers," the mysteries of the heavens is what draws them to this hobby. Just imagine how it feels if you, with your telescope, discovered that a asteroid or comet was headed towards earth! Imagine discovering a new comet before anyone else or unraveling the mysteries of a pulsating star in the next galaxy. All this and more are what astronomer look for when they scan the sky.
