Asteroids are small, rocky objects that orbit the Sun. Most are located between the orbits of Mars and Jupiter. This area of our Solar System is known as the Asteroid Belt.

Go Observing includes advanced options where you get to decide the exposure time of the observation and the filter the telescope uses.

Did you know that what you weigh depends on the strength of gravity? And did you know that the strength on gravity on other planets is not the same as on Earth?

You have likely heard about the Universe expanding. Or that redshift can tell us about the movements of galaxies. Both are difficult ideas to imagine and understand.

Is gravity the same everywhere? Experiment with how the ball reacts in each of the Solar System locations by dropping or throwing the ball. How similar or different is each location to Earth?
