Did you know you can see an asteroid using binoculars? This month, look for the brightest asteroid of all, called Vesta, making its way across the night sky. Asteroids are relatively small celestial bodies made up of rock, which mainly orbit the sun in a belt between Mars and Jupiter. Vesta is the second biggest object in this asteroid belt, with a diameter of 525 km. The biggest asteroid by far is Ceres, which has a diameter of 945 km, and in third place is Pallas, diameter 512 km.
