NASA alerts truck-sized asteroid destination Earth and will arrive the day before the US presidential election - An asteroid has a small chance of entering the Earth's atmosphere on November 2, the day before the US presidential election, NASA has announced.

Called '2018VP1', the asteroid is small, with an estimated diameter of between 1.8 and 3.9 meters, according to data from the space agency.

It has only a 0.41% chance of impacting the Earth and, however, celestial objects of that size usually burn in the atmosphere.

"The asteroid 2018vp1 is very small, about 2 meters, and poses no threat to Earth," a NASA spokesman told Business Insider. "If it entered the atmosphere it would disintegrate because of its size."

2018VP1 has been close to Earth at other times since 1970. His last visit was in November 2018, when he was discovered at the Palomar California Observatory.

NASA data shows that, after two years around the sun, it will again pass between 7,000 and 400,000 kilometers of the atmosphere. As a reference, the International Space Station is located about 400 kilometers above the planet.

The size of asteroids like this makes them difficult to detect until they are already close to Earth, but most pass long, even far from the Moon, explains a recent statement from NASA.

In fact, another asteroid called 2020 HQ passed just 2,900 kilometers from Earth, over the Indian Ocean, and NASA didn't even see it coming

In 2005, Congress ordered NASA to discover 90% of potentially dangerous asteroids over 140 metres in diameter by the end of 2020.

"It's quite an achievement to find these tiny asteroids because they pass so fast," explains Paul Chodas, director of the Center for Near-Earth Object Studies (CNEOS) at NASA's Laboratory in Southern California.

"Normally, there is a period of a couple of days when asteroids of this size are close enough to Earth to be visible but not so close that they move too fast and cannot be detected with a telescope," he said.

With the coronavirus pandemic, protests for racial Justice, depression and anxiety over the clouds, the election campaign and other recent events, people joke about the asteroid and say it embodies the year 2020.

Researchers document the first case of coronavirus reinfection from around the world: a Hong Kong man tested positive again on COVID - 19 on his return from a trip to Spain

A study by researchers at the University of Hong Kong claims that a man re-infected with coronavirus after passing the disease, which would make it the first documented case of reinfection.

The patient, a 33-year-old man, suffered the disease in April and has returned positive earlier this month after returning from a trip to Spain.

"Our findings suggest that SARS-CoV - 2 may persist in the global human population as is the case with other human coronaviruses associated with the common cold, even if patients have acquired immunity through a natural infection," the authors note in a statement collected by the New York Times.

These results would confirm that the immunity that is acquired against the new coronavirus is not lasting, something that the researchers ask to take into account when organizing vaccination campaigns, recommending also vaccinate those who have passed the disease.

Several experts previously consulted by Business Insider Spain have been sceptical about the possibility of reinfections occurring.

The first cases came from South Korea, which claimed that the new positives were due to the fact that the virus, no longer capable of infection or contagion, remained in the patient's body and was detected by the tests, but that there was no reinfection.

However, to rule out that hypothesis in this case, Hong Kong researchers have sequenced the virus from the two cases of infection and found significant differences between the two, suggesting that the patient was infected a second time, they have claimed.
