Whats the Difference Between a Planet and a Moon?
What’s our Sun? Our Sun is a star. This means that, like any star, the Sun formed down from a dust and gas cloud, and that it’s a thermonuclear factory where hydrogen is transformed into helium. CAUTION! Observing the Sun is dangerous and requires dedicated safe techniques! What are NEOs? Near-Earth Objets (NEOs) are asteroids or comets orbit of which may represent a hazard to the Earth. Such objects might one day hit Earth in the same way that some already hit, bringing e.g. to the extinction of the dinosaurs 65 million years ago, or on a lesser scale, to the Tunguska event, at the beginning of the 20th century, when 1200 square miles forest were destroyed in Siberia, Russia. Research program are underway to catalog all such hazardous objects. None until now have been found to be directly threatening although some are forecasted to come very close to Earth What’s the Asteroid Belt? The asteroid belt is a swarm of minor planets -or “asteroids”- which is found between the orbit of Mars
