A newly-discovered asteroid is projected to fly safely by Earth on Wednesday. Discovered April 11, Asteroid 2020 GH2 is anywhere from 43 to 70 feet wide or about the size of a single-family house, according to Space.com.
How would NASA stop an asteroid?
An object with a high mass close to the Earth could be sent out into a collision course with the asteroid, knocking it off course. When the asteroid is still far from the Earth, a means of deflecting the asteroid is to directly alter its momentum by colliding a spacecraft with the asteroid.

Is there an asteroid coming in 2020?
Asteroid 2020 QG enters the record books as the closest known nonimpacting asteroid; many very small asteroids impact our planet every year, but only a few have actually been detected in space a few hours before impacting Earth. On average, an asteroid the size of 2020 QG passes this closely only a few times a year.

Who owns the moon?
The Outer Space Treaty means therefore that – no matter whose national flags are planted on the lunar surface – no nation can ‘own’ the Moon. As of 2019, 109 nations are bound by the Treaty, and another 23 have signed the agreement but have yet to be officially recognised.
What planet rains diamonds?
Deep within Neptune and Uranus, it rains diamonds—or so astronomers and physicists have suspected for nearly 40 years. The outer planets of our Solar System are hard to study, however. Only a single space mission, Voyager 2, has flown by to reveal some of their secrets, so diamond rain has remained only a hypothesis.
Does NASA use gold?
Gold is also used by NASA in the construction of spacesuits. Because of its excellent ability to reflect infrared light while letting in visible light, astronauts’ visors have a thin layer of gold on them to protect their eyes from unfiltered sunlight.
