Tauranga Astronomical Society presents “Astronomy 101” – our fun and interactive introduction to the solar system, planets, stars and beyond! Join us as we compare the size of moons, planets and stars. How big is the Moon compared to the Earth? How far away is the Moon? How big is the Sun? Try our Gravity Simulator and see how many times your planet can orbit the Sun. Check out our model rockets and much more – Fun for all ages!
