2 Big Asteroids Flying by Earth Pose no Risk: NASA

At the start of 2019, the number of discovered NEOs totaled more than 19,000, and it has since surpassed 20,000. An average of 30 new discoveries are added each week, NASA said

NASA has ruled that the pair of asteroids flying by Earth this weekend could pose a threat to our planet.

“These asteroids have been well observed – once since 2000 and the other since 2010 – and their orbits are very well known,” said NASA’s Planetary Defence Officer Lindley Johnson.

“Both of these asteroids are passing at about 14 lunar distances from the Earth, or about 3.5 million miles away, but small asteroids pass by Earth this close all the time,” Johnson said.

Near-Earth asteroid 2010 C01, estimated to be 120 to 260 metres in size, safely passed Earth at 3.42 a.m. on Saturday. The second object, 2000 QW7 is estimated to be 290 to 650 metres in size will pass later at 11.54 p.m. on Saturday.

Near-Earth objects (NEOs) are asteroids and comets that orbit the Sun, but their orbits bring them into Earth’s neighborhood – within 30 million miles of Earth’s orbit.

These objects are relatively unchanged remnant debris from the solar system’s formation some 4.6 billion years ago.

Most of the rocky asteroids originally formed in the warmer inner solar system between the orbits of Mars and Jupiter, while comets, composed mostly of water ice with embedded dust particles, formed in the cold outer solar system.

At the start of 2019, the number of discovered NEOs totaled more than 19,000, and it has since surpassed 20,000. An average of 30 new discoveries are added each week, NASA said. (IANS)

NASA is closely monitoring an asteroid with an estimated diameter of about 755 feet — larger than the Golden Gate Bridge tower or more than twice the height of London’s Big Ben — that is currently heading towards Earth and is expected to skim past the planet on Monday.

Flying towards the planet at a speed of over 61,500 miles per hour, the Near-Earth Object (NEO) is big enough to destroy an entire city if collides with the Earth.

The approaching asteroid has been identified as “2020 AQ1”.

According to Express.co.uk, the asteroid will make its closest Earth approach on January 20 at around 2.54 am EST (1.24 pm India time).

The European Space Agency (ESA) has identified 21,655 NEO asteroids and 109 NEO comets.

The asteroid will hurtle past the planet on what astronomers have described as a “close approach” trajectory.

NASA’s trackers estimate the rock measures somewhere in the range of 328 feet -754 feet across – more than twice the height of London’s Big Ben.

Last September, a pair of asteroids flew past the Earth.
