It is called (7335) 1989 JA (because it was discovered in 1989) and it is 1.8 kilometers long. he is bigger potentially dangerous asteroid that will pass near the Earth in 2022. But don’t worry, there is no risk that it will annihilate the biospherebecause it will pass about 4 million kilometers from Earth, a very safe distance that is equivalent to more than 10 times that which separates us from the Moon.
In the large family of asteroids that cross Earth’s path, the NEOand which has 29,000 members, 1989 JA is among the 878 largest, specifies the POT who studied his orbit (2.4 years) and determined that this passage on May 27, precisely at 14:26 UT (16:26 Paris time), will be the closest for the next 172 years.

If you want to see it live, the virtual telescope will broadcast its observations from Chile this Friday, May 27, starting at 01:00 Paris time (23:00 GMT on May 26), and from Australia starting at 15:00 Paris time.

This 600-meter asteroid will pass close to Earth tomorrow
article of Xavier Demeersmann published on December 25, 2019
AN asteroid It measures between 300 and 620 meters at its greatest length and will pass close to Earth on December 26, after sunrise. The Sun is the closest star to Earth, from which it is approximately 150 million kilometers away. The Sun is 8.5 kparsecs from the center of the Milky Way. In stellar classification, the sun is a G2-type star.

So there is nothing to fear because the closest one to us, at 7:54 a.m. UT (8:54 a.m. Paris time), will be just over seven million kilometers from Earth. In other words, it will “pass” us at almost 19 times the distance from A moon with a lowercase “L” is the satellite of a planet. For example Phobos and Deimos are the two moons of the planet Mars.

In short, the risk of this “big rock” colliding with Earth is very low. In addition, let us note in passing that this very week – and this is the case throughout the year – asteroids, certainly smaller, will venture even closer to Earth. From NEO indicated on the site Gnaeus NASA For example: 2019 WB7 (recently discovered), with a diameter estimated at the moment between 30 and 70 meters, will pass closest to us, at 2.7 times the distance of the Moon on December 23.
Considered a potentially dangerous asteroid -because of its size and because it passes less than 7.5 million kilometers from our biosphere-, 310442 (2000 CH59), or CH59 for short, remains a closely watched “target” by space agencies who want to avoid the possibility of a mid- to long-term collision course.

An asteroid 570 meters wide passes closest to Earth on Saturday
Article by Xavier Demeersman published on August 9, 2019
Here is 2006 QQ23. On Saturday morning, August 10 (around 9:30 a.m. Paris time), this large asteroid approximately 570 meters in diameter it will pass closest to Earth, at 7.5 million kilometers. This distance that corresponds to 0.05 The Big Bang to Life site…” data-image=”https://cdn.futura-sciences.com/buildsv6/images/midioriginal/4/e/0/4e0655d484_50034138_solarmap. jpg ” data-url=”https://news.google.com/sciences/definitions/universe-astronomical-unit-63/” data-more=”Read more”>astronomical unitsthat is, equally 19.5 times what separates us from the Moon, is the maximum limit given by the Center for Near Earth Object Studies (CNEOS) of NASA to classify a NEO of this size as a “potentially dangerous object”. In this specific case, therefore, we have nothing to fear from this celestial body (discovered in 2006) that is millions of kilometers away from our planet. It does not have, for the moment, anything dangerous or threatening. And fortunately, because if it had been on a collision course, there is no doubt that the impact would cause significant damage on a regional scale, and with global consequences.
Aware of the risks, many scientists have asked the international community in recent years to redouble our vigilance and, therefore, the technical means necessary to avoid losing an untimely visitor who could explode on a city or even a sensitive building. ..
The passage, on July 25, of 2019 good only 65,000 kilometers from the surface of the earth, it correctly reminded humanity of this again. Discovered a few days earlier, no one had seen this 100-meter-long asteroid coming. As always, it is the smallest ones that are the most difficult to detect. The largest ones that cross the Earth’s orbit are almost all known, think of the astronomers. They are about 900 and very few are likely to go dark on Earth. So we need more eyes in the sky!
Should we be afraid of this asteroid that is skimming the Earth?
Article by Xavier Demeersman, published on June 27, 2019
As tall as the Eiffel Tower, the asteroid 2008 KV2 it is a visitor that has passed close to Earth many times over the centuries, unnoticed (it was only discovered in 2008). It is a near-Earth cruise ship whose 286-day orbit regularly brings it close to Venus and also of our planet.
Due to its size (estimated at 330 meters) and its approach to less than 7.5 million kilometers from our Blue Planet, 2008 KV2 is therefore considered a ” potentially dangerous object “But rest assured that it is not tonight that it will hit the Earth, not even during its next passage, in 2021. In fact, for its visit on the night of June 27-28, closer to 22:01 UT, i.e. 00:01 Paris time, will venture to a safe distance of 6.7 million kilometers… In other words, at most close to earth, it will be 17.7 times further away than the Moon. So nothing to fear. Naturally, NASA maintains it.eyefollowing his path in each of his steps, his own and that of his many already known congeners.
