Saturday night, a 300 and 600-meter space rock will fly to Earth. To determine its size, the Willis Tower in Chicago is 412.7 meters tall.
Specialists claim that the space stone, known as Asteroid 2000 QW7, will miss our planet about 3 million kilometers, several times the separation between Earth and the Earth. Moon. And keeping in mind that this separation is surprisingly close on the cosmic scale, it does not say that space rock will hit the Earth – despite the fact that it is lucky to hit our planet later. The proximity of his pass Saturday will allow space experts to sharpen their estimates of his direction, taking into account later the precision of the accuracy of his chances of striking.
Gianluca Masi, scientific director of The Virtual Telescope, told Salon that space novice experts could see his flyby, which is at 19:54 on the East Coast, but that he should have a telescope of 39, an exceptional magnitude. 250 millimeters. Masi said that a small telescope could work if it was associated with a tactile imaging gadget able to record its obvious movement over the stars.
"At about the time of the crossing, the rock will be about 8 degrees south-southwest of the bright star Fomalhaut," Masi said in an email. "An exact position can be retrieved from the JPL Horizons website here."
The specialists of the B612 Foundation, a non-profit organization whose mission is to protect the Earth from space radiation, say that it does not pose a threat to our planet today, but that it could be done in a future inaccessible because its circle will cross it and no longer go near the Earth. Space Rock 2000 QW7 was first discovered by NASA's cosmologists on August 8, 2000.
NASA made an announcement this week to the general public to emphasize that it was anything but a danger, noting that it was really one of two rocks in space to pass on Earth this weekend. The next rock, the 2010 C01, is estimated to be 120 to 260 meters (400 to 850 feet) in size.
"These space rocks have been the subject of constant surveillance – one since 2000 and the other since 2010 – and their circles are very remarkable," said Lindley Johnson, head of Planetary and Responsible Protection for the NASA Global Defense Coordination Office Program, in a statement. "These two space rocks are at about 14 good lunar distances from the Earth, about 3.5 million kilometers, but small rocks are constantly passing through the Earth near this Earth."
The B612 Foundation experts say that these space rocks are an update that we should develop later to redirect potentially dangerous to Earth.
"We are 100% sure that we will be affected, but we are not 100% sure, so we need to accelerate the pace of disclosure of space," said Danica Remy, president of the B612 Foundation, in a statement. a proclamation in the media.
As recently revealed Salon, the subsidy is probably the main obstacle to speeding up the disclosure of spatial information and diversion
"This is a perfectly reasonable problem," said Danica Remy, president of the B612 Foundation, at Salon in 2018. "When you look at huge problems around the world, you will not be able to understand as much. . . . Whatever it is, [asteroid impact] is [a] smaller [problem] contrast with famine or war or change in the environment. "
John Carrico, an astrophysicist at B612, told Salon that new computing capabilities have allowed researchers to better understand what kinds of space rocks can and can not be distinguished and mapped using specific telescopes. In any case, it is expected that larger telescopes will recognize each rock close to space, especially the smaller ones whose effects could destroy urban communities without causing the destruction of planet.
"Basically, we have just discovered the huge space rocks up here, in light of the fact that they are simpler to see with a telescope," Carrico said. "We need all the most dominant telescopes to see the smallest […] There may be dozens, hundreds, thousands of space rocks, and we have no idea where they are, but they could crush a city or create a tidal wave, "he said. he adds.
