An extraordinary and bright object was spotted streaking through the skies over Russia before it detonated around 97,000 feet over the Earth's surface on Feb. 15, 2013. The subsequent blast harmed a huge number of structures and harmed around 1,500 individuals in Chelyabinsk and the encompassing zones. While this seems like the main scene of a sci-fi motion picture, this intruder wasn't an outsider spaceship assaulting humankind, however a 20-meter-widespace rock that had crashed into the Earth. The major concern is that nobody had any thought this 20-meter asteroid existed until the point when it entered the Earth's environment that morning. Astronomers study the objects in the sky that change in terms of brightness over a short period of time. The majority of their research is focused upon the enhancement of the telescopes and its operation to observe the constantly changing sky. That is critical in light of the fact that similar telescopes that are used to investigate other star systems are additionally being intended to enable the team to discover objects in in the solar system, such as asteroids on a collision course with Earth.
A meteor is any piece of matter that enters the atmosphere of the Earth. Prior to the Chelyabinsk meteor met the Earth, it was rotating around the sun as an asteroid. These rough questions are ordinarily thought to be confined to the asteroid belt among Mars and Jupiter. Nonetheless, there are numerous asteroids in the solar system. A few, similar to the Chelyabinsk meteor, are referred to as near-Earth objects (NEOs). The Chelyabinsk meteor likely originated from a group of NEOs called Apollo asteroids, named after the space rock 1862 Apollo. There are over 1,600 known Apollo asteroids present in the JPL Small-Body Database that have circles that may cross the Earth's way, and are huge enough (more than 140 meters), that they're potentially hazardous asteroids (PHAs) in light of the fact that a collision with Earth would demolish the area that is hit. The government in the United States is taking an asteroid collision into consideration. In Section 321 of the NASA Authorization Act of 2005, Congress needed NASA to build up a program to scan for NEOs. NASA was appointed the errand of detecting 90 percent of all NEOs more prominent than 140 meters in diameter. Presently, they assess that seventy five percent of the 25,000 PHAs presently can't seem to be found.
