Detailed explanation-1: -What do asteroids have in common with Earth? They rotate around the central axis. How old are asteroids compared to the rest of the solar system? There’re about the same age as the rest of the solar system.
Detailed explanation-2: -Asteroids are small, rocky objects that orbit the Sun. Although asteroids orbit the Sun like planets, they are much smaller than planets. Asteroids are small, rocky objects that orbit the sun. Although asteroids orbit the sun like planets, they are much smaller than planets.
Detailed explanation-3: -Orbit and Rotation Bennu makes one orbit around the Sun every 1.2 years. It makes one full rotation on its axis every 4.3 hours.
Detailed explanation-4: -Comets and asteroids have a lot in common. Both orbit the sun. Both are far smaller than the planets. Both are remnants of the solar system’s formation almost 5 billion years ago.
Detailed explanation-5: -They have rotation periods between 7.4 minutes and 6.8 hours and diameters between approximately 28 metres (92 feet) and 2.5 km (1.6 miles). A rotating asteroid shows a light-curve amplitude of zero (no change in amplitude) when its shape is a uniform sphere or when it is viewed along one of its rotational axes.
