NASA (National Aeronautics and Space Administration) has warned that a giant asteroid is going to pass earth on July 24, 2020. As per NASA, it is larger than the famous London eye which is about 443 feet high and will make near to the earth. NASA said on their website that, “Potentially Hazardous Asteroids are currently defined based on parameters that measure probable to make threatening close approaches to the Earth”. They also added, “Specifically, all asteroids with a minimum orbit intersection distance (MOID) of 0.05 astronomical units or less and a complete magnitude of 22.0 or less are considered PHAs.
The space experts in the United States have named the space rock Asteroid 2020ND and have been marked as “likely hazardous”. The rock measuring 170 meters will come within just 0.034 astronomical units (AU) of our planet. One AU (149,598,000 km) is the distance between the Earth and the Sun. It is expected that on coming Saturday, the asteroid which is traveling at a reel of 13.5 kilometers per second or 48,000 kilometers per hour will be 5,086,327 kilometers away from our planet.
“NEOs are the asteroids and comets which are been dig by the gravitational attraction of nearby planets into the orbits which allows them to enter the Earth’s area. This comets and astroids are discovered almost 4.6 billion years before in the solar system”, NASA recently wrote on its Jet Propulsion Laboratory (JPL) website.
The facts about Asteroids:
- Asteroids are miniature, rocky objects which revolve around the Sun.
- In 1801, the first asteroid called Ceres was discovered by Giuseppe Piazzi.
- The care is about 933 kilometers (580 miles) across. The smallest known asteroid, BA 1991, is only 6 meters (20 feet) across.
- Presently, there are more than 8,30,000 known asteroids in our solar system.
- Most asteroids orbit and belts, which are a series of rings between the orbits of Mars and Jupiter.
- “Star-like” term first given by Astronomer William Herschel in 1802.
- An object formed by rock, dust, and other materials that never absorb in one of the eight planets in our solar system.
- Apollo objects are asteroids whose orbit passes through the Earth’s orbit.
- Most of them are different in shape because they are too small to exert enough gravity to become spherical.
- Some of them are blown out comets. When the ice vanishes, all of that remains in the rock material.
- Car-sized meteors fall into the Earth’s atmosphere once a year on average. This produces a bright fireball effect, but it usually burns in the atmosphere before reaching the ground.
- According to scientists, the crash of the asteroid about 65 million years ago caused a chain reaction which leads to the disappearance of the dinosaurs and affected all life on Earth.
