Green comet and asteroid OSIRIS-REx will dazzle in 2023
Asteroids are known as rocky celestial bodies that revolve around the Sun., Astronomers can see them through telescopes and according to previous research they usually orbit Galaxyand very close to the systems of mars and jupiterwhere the asteroid belt is recorded. NASA identifies them as small rocky bodies, better recognized as remnants of the formation of the Solar System, which appeared with the collapse of a large cloud of gas and dust about 4.6 billion years ago. “Some of the condensed dust within the cloud became planets. Objects in the asteroid belt never had a chance to coalesce into planets, and they are remnants of a distant time when planets formed.” National Aeronautics and Space Administration explains.
Asteroids are not round like planets. They have jagged and irregular shapes.
Some asteroids are hundreds of kilometers across, but most are as small as a pebble.
– Most are made of various types of rock, but some contain clay or metals, such as nickel and iron.
the figure! In 2016, NASA launched the spacecraft Osiris-Rex To study the near-Earth asteroid named Bennu. After studying Bennu for a few years, OSIRIS-REx collected a sample of dust and rocks from the asteroid’s surface. Now, OSIRIS-REx is on its way back to Earth! Your sample container will land in the Utah desert September 2023, Scientists will then collect the container and examine the dust and rocks for clues about how the planets formed and life began.
