Map of asteroids in the solar system for nearly 20 years
NASA's simulated map shows a growing number of asteroids near the Earth and in the belt between Mars and Jupiter.
NASA announced the video illustrating the asteroids discovered from January 1, 1999 to January 2018, Space announced on July 24. Accordingly, the number of near-Earth asteroids (NEA) , located in the space of about 50 million km from Earth orbit, increased markedly every 10 years.
In 1999, asteroids were found to be sparse. After 10 years, scientists have identified many more asteroids and by 2018 the number has increased significantly. The space around the Earth is actually much more "crowded" . Astronomers have so far discovered about 18,000 objects near the Earth (NEO) , including comets, but the estimated total could reach millions.
The NEO observation program was born in 1998 and discovered about 90% of the 18,000 NEO.
In addition, the video also shows known asteroids in the main belt between Mars and Jupiter. The belt contains a large portion of more than 780,000 asteroids that humans identify, according to NASA.
NASA has found and monitored about 95% of asteroids more than a kilometer close to Earth, in which no asteroids are truly dangerous in the near future. NASA's NEO observation program is also working to realize the goal of tracking and tracking 90% of objects close to Earth over 140 meters wide by 2020. Scientists estimate that only one third of them have been identified. object of this type.
The NEO observation program was born in 1998 and discovered about 90% of the 18,000 NEO, NASA said. The program's research and data analysis site is the Near-Earth Research Center (CNEOS) at NASA's Jet Propulsion Laboratory in Pasadena, California, USA.
"We calculate the trajectory of all asteroids or comets with high precision and map their position in the solar system, tracking the future path to detect the risk of collisions and the way. We used to see where they used to be, we gave the best trajectory map of small known objects in the solar system, " said Paul Chodas, director at CNEOS.
