MASSACHUSETTS, NNC – Astronomers have lost track of nearly 900 asteroids near Earth. The researchers can not keep track of the asteroids, which means that astronomers can not know if they are on a collision course with Earth or not.
Despite fears that asteroids could hit Earth, experts hold low potential Earth asteroids that cause damage.
Near Earth asteroids (NEAs) are space rocks that are within 48 million kilometers of Earth orbit. So far, astronomers have seen more than 8,000 asteroids near Earth that are at least 1
Between 2013 and 2016, 17,030 NEAs were registered by the Minor Planet Center of the International Astronomical Union in Cambridge, Massachusetts. Of these, 11 percent, or nearly 1,900, were initially unconfirmed, meaning that the asteroids were observed several times, but not enough to align their orbits.
In a new study, researchers at the Minor Planet Center researched data to find out why astronomers lost track of so many objects. They found that astronomers were often too slow to track their orbits.
NEAs are typically chosen by an asteroid survey system that uses telescopes that scan most of the night sky with artificial intelligence (19659003) results confirm the secondary sources, and the researchers found that the delay between these two measurements is often the same The reason is why NEAs are missing.
Some telescopes take more than 20 hours to report the potential of NEAs, making them nearly impossible to find (19659003) "We need to act fast, tomorrow it could be on the other side of the sky, and nobody knows where it is, "said the lead author.

To determine their findings, the team examined data from some of Earth's most prolific asteroid hunting systems, including Pan-STARRS, Catalina Sky Survey, Dark Energy Survey and Space Observation Telescope
