Asteroid News: Asteroid of the size of Burj Khalifa coming towards the earth at a speed of 22 thousand km per hour

Learn on Asteroid Day, what are these huge rocks coming from space, how dangerous?


  • NASA has warned that the giant 250-meter asteroid has been towards the Earth’s orbit
  • This asteroid the size of Burj Khalifa will pass near the Earth’s orbit on July 1
  • NASA said that the 2021 GM4 asteroid could be between 110 and 250 meters wide

The US space agency NASA has warned that the giant 250-meter asteroid is moving towards the Earth’s orbit at a speed of 22 thousand km per hour. This asteroid will pass very close to Earth’s orbit on July 1. NASA has been keeping a close eye on this asteroid since 2006. This asteroid is twice the size of the London Eye and the Burj Khalifa building in Dubai. This asteroid has been named ‘2021 GM4’.

NASA said that the 2021 GM4 asteroid could be between 110 meters and 250 meters wide. This asteroid was first identified on 10 October 2006. A similar massive asteroid 2020 DM4 passed near Earth’s orbit in May 2020. This asteroid is currently traveling at a speed of 6.29 km per second. Based on the estimates of scientists, this asteroid 2021 GM4 will reach near Earth’s orbit on Thursday, July 1.

There are 22 such asteroids that are likely to hit the Earth
NASA has placed it in the category of dangerous asteroid. This asteroid is the third of 5 to come in recent times. It is estimated that this asteroid could be the size of the Burj Khalifa building in Dubai. These days, NASA is keeping an eye on two thousand asteroids which can become a threat to the Earth. If a high-speed space object is likely to come closer than 46.5 million miles from Earth, then space organizations consider it dangerous. NASA’s Sentry system already monitors such threats. In this, for the coming 100 years, there are currently 22 such asteroids which have the slightest chance of hitting the Earth.

What are Asteroids?

Asteroids are rocks that revolve around the Sun like a planet, but they are much smaller than planets in size. Most of the asteroids in our solar system are found in the asteroid belt in the orbit of Mars and Jupiter. Apart from this, they keep moving in the orbit of other planets and revolve around the sun along with the planet. About 4.5 billion years ago, when our Solar System was formed, such clouds of gas and dust that could not take the shape of a planet and were left behind, were transformed into these rocks i.e. asteroids. This is the reason that their shape is also not round like the planets. No two asteroids are alike.
