The first human-made object collides with another planet without control

Image
 For the first time in history, a human-made object collides or falls on another planet without intention or control. The beginning was in February of 2015, the US space agency NASA and the US National Oceanic and Atmospheric Administration NOAA launched a rocket into space carrying a new satellite to an altitude of 1.5 million kilometers outside the surface of the Earth. The satellite's mission was to monitor the activity of Solar Storms, and the atmosphere of the planet in general. After it reached its place and the mission succeeded, the Falcon-9 rocket from Space-X unexpectedly ran out of fuel, and the second stage separated from it to enter into orbit out of control. F or 7 years, the rocket, which weighs 4.4 tons, revolves in a complex and unpredictable orbit around the Earth, affected by the Earth's gravity, and the gravity of the sun and the moon together. Recently, according to the latest calculations of the missile's orbit, it is expected that it will collide wi...

  On April 27, 2016, a small asteroid was discovered around the Earth by the Pan-STARRS 1 asteroid survey telescope on Haleakalā, Hawaii, that is operated by the University of Hawaii's Institute for Astronomy and funded by NASA. The asteroid named Kamoʻoalew is a word in the language of the ancient Hawaiian tribes, meaning: "a moving space object." Scientists initially thought it was an ordinary asteroid, until they discovered that it is actually orbiting around the planet, in a giant orbit that takes it at a distance of more than 38 to 100 times the distance between the Earth and the moon, and when the asteroid was examined through the telescope, scientists found that it is formed from common silicate that all asteroids are made of, but when examined with infrared telescopes, it was found that the fingerprint of that asteroid, which is visible in this infrared, is completely different from the rest of the asteroids that were almost all discovered. Then the scientist Ben ...
