An asteroid about as long as the Great Pyramid of Giza is tall made a “close” approach with Earth on Sunday (July 25), according to NASA calculations.

There is no worry that the space rock poses any threat to Earth, but NASA monitors such rocks to both learn more about the early solar system — asteroids are rocky fragments from that time — and because if their orbits were to change, the asteroid could pose a future risk to Earth.

NASA finally approves the launch of an infrared asteroid hunting space telescope able to locate threats 30M miles away…

NASA has approved the Near-Earth Object Surveyor space telescope to help the space agency be better prepared for future asteroids that could pose a threat to Earth.

The 20-foot-long infrared telescope would help astronomers and planetary scientists find ‘most’ of the potentially hazardous asteroids and comets that come within 30 million miles of Earth’s orbit, also known as near-Earth objects (NEOs).

According to NASA, there are just over 25000 NEOs, but many more are waiting to be discovered.

By knowing where meteorites come from, we can protect the Earth from asteroid collisions.

After examining 10000 kilograms of sedimentary rock, a new study suggests that meteorites come from an unidentified region in the asteroid belt.

Scientists around the world have been bamboozled this week by a fictitious asteroid heading toward Earth.

A group of experts from US and European space agencies attended a week-long exercise led by NASA in which they faced a hypothetical scenario: An asteroid 35 million miles away was approaching the planet and could hit within six months.

WASHINGTON — NASA’s OSIRIS-REx spacecraft will make one final close approach to the asteroid it collected samples from next week before heading back to Earth.

On April 7, the spacecraft will pass 3.7 kilometers above the location on the asteroid Bennu called Nightingale where, in October, the spacecraft briefly touched down and collected as much as several hundred grams of material, now stored in the spacecraft.

Immediately after that sample collection maneuver, the mission had no plans to return to the vicinity of Bennu. However, NASA decided to make a final pass over the touchdown site to see what changes the sampling made to the Nightingale region, like the creation of a crater.

A collision between Earth and the asteroid 99942 Apophis can be ruled out, for at least the next century, based on new observations by NASA.
