In 2022, a giant asteroid will pass by Earth at an alarming rate, with the potential to destroy all life on our planet. The asteroid is called 2002 AJ129 and is about 3,000 feet long and 650 feet wide. To be clear, there is no chance that your Earth-bound electronic devices will be working when this happens.
Yes, asteroids have hit Earth over the course of its history, and it will happen again. Dust, meteoroids, and even small asteroids hit Earth all the time and they create the meteors or “shooting stars” that you see as they disintegrate in the atmosphere.

The next time the asteroid will come this close to Earth will be in 2105 when it will fly 0.01556 AU, roughly 1.4 million miles, away from Earth.

NASA knows of no asteroid or comet currently on a collision course with Earth, so the probability of a major collision is quite small. In fact, as best as we can tell, no large object is likely to strike the Earth any time in the next several hundred years.
Apophis isn't going to strike our planet on April 13, 2029, but scientists think that the effect on it of the close pass could be to alter its trajectory—and dangerously so. It's possible that Earth swing-by could put it on an Earth-resonant impact trajectory that come 2060 or 2068.
1.1 miles longA "potentially hazardous" asteroid measuring more than a mile long will zoom past Earth this week, the largest asteroid expected to get relatively close to our planet in 2022. The asteroid, named 1989 JA, is estimated to be 1.1 miles long, or 5,905 feet, according to NASA's Center for Near Earth Object Studies.
What would happen if Apophis hit Earth? Apophis would cause widespread destruction up to several hundred of kilometers from its impact site. The energy released would be equal more than 1,000 megatons of TNT, or tens to hundreds of nuclear weapons.
A recently discovered 1,300-foot-wide (400 meters) asteroid that passed near Earth last month could pay the planet another close visit in 2032. But, NASA officials say there is nothing to fear, as the odds that the space rock will hit Earth are extremely slim.

One of the closest approaches is Asteroid 2021 TJ15, which will pass the Earth at the same distance at the moon, or 238,854 miles away, on Saturday. "That asteroid has a diameter of 5.6 to 13 meters (18 to 42 feet). That's a tiny asteroid coming to about the distance of the moon.
The Earth is safe from the giant asteroid Apophis when it flies extremely close to our planet in 2029, then returns for seconds in 2036, NASA scientists announced today (Jan. 10). The chances of an impact in 2036 are less than one in a million, they added.
NASA announced two new missions, and ESA announced one: VERITAS: NASA's VERITAS, or Venus Emissivity, Radio Science, InSAR, Topography, and Spectroscopy, will be the first NASA spacecraft to explore Venus since the 1990s. The spacecraft will launch no earlier than December 2027.
Therefore, the chance that such an object will hit us in any given year is roughly 1 in 300,000 -- nothing to lose sleep over.
Comet Lemmon-Panstarrs shows a hint of an eastward-pointing tail on March 24, 2022. The comet is relatively bright but low in the west at dusk. While 2022 has its share of comets, only a few are expected to reach magnitude 8 or brighter and become fair game for smaller telescopes and binoculars.
