The REVEALS map shows a dramatic increase in NEAR-EARTH asteroid discovery

This map reveals how thousands of other near – Earth asteroids – which would cause "devastation" – were detected by NASA.

NASA produced an animation showing the scale of space rocks that she discovered between 1999 and today.

Astronomers have found about 18,000 objects, including comets clbadified as near-Earth objects that are less than 30 million miles from the orbit of our planet around the Sun.

And he has an ambitious program to discover 90% of objects close to Earth, which are at least 450 feet wide, in the next few years.

SPACE AGENCY: NASA has discovered thousands of near-Earth asteroids over the past 20 years

Despite their small size, the agency admitted that these galactic objects could still cause destructions they hit the cities

Paul Chodas, of NASA's near-earth studies center, said: "These smaller asteroids do not pose a global disaster threat if they affect the Earth, but they can cause considerable damage and loss of life.

The NASA Near-Earth Object Study Center performs accurate orbit calculations based on data from Observatories around the world that detect and track the movement of asteroids and comets

closely monitor any potential asteroid of danger, including those crossing the orbit of the Earth.

"We calculate orbits of high accuracy for all asteroids and comets and map their positions in the s "We provide the best orbital map for all known small bodies in the solar system," said Mr. Chodas

.

The new 20-year animation shows how NASA's understanding of the solar system has improved mbadively as it celebrates its 60th anniversary on Sunday.

Blue in the animation, which represents the asteroids close to the Earth, changes considerably from the 1999 point of view to present day

The orange represents the asteroids of the belt main, of which they are estimated at 780,000, between the orbit of Mars and Jupiter.
