Asteroid Dinkinesh

Asteroid Dinkinesh:

NASA’s Lucy spacecraft, on a mission to observe Jupiter’s Trojan asteroids, recently made an unexpected discovery.

  • It found that the main belt asteroid Dinkinesh, which it was set to fly by, is actually a binary system of two asteroids bound together.
  • Preliminary analysis suggests that the larger asteroid is about 790 meters wide, while the smaller one is approximately 220 meters in size.
  • An asteroid is a rocky, metallic, or icy minor planet that orbits within the inner Solar System.
  • Asteroids are smaller than planets but larger than meteoroids. They can range in size from 1-meter rocks to a dwarf planet almost 1000 km in diameter.
  • Asteroids are remnants left over from the early formation of our solar system about 4.6 billion years ago.
  • Most of them can be found orbiting our Sun between Mars and Jupiter within the main asteroid belt.
  • Asteroids are also known as minor planets or planetoids.
  • The larger forms of asteroids are also known as planetoids.
