Space. This asteroid approaches Earth once a century… And it’s in less than two weeks

(7482) 1994 PC1 is the nickname of this asteroid larger than the tallest tower in the world, the Burj Khalifa. It is one kilometer long and is considered a “potentially dangerous asteroid” because it regularly approaches Earth, reports the ScienceAlert website.

On Tuesday, January 18, it will approach Earth. But no risk: the researchers calculated that it would pass 1.93 million kilometers from us, that is to say more than five times farther than the Moon. And the calculation margin of error is just over 100 kilometers.

Observable with a small telescope

Its last passage close to Earth dates back to 1933 (although it was discovered in 1994), and the next one is expected in 2105. This January 18 is therefore an opportunity not to be missed for space observation enthusiasts. It will not be possible to see it with the naked eye, but a small telescope should suffice. This site tells you everything you need to know to observe it. It will look like a star, but we can see it spinning at nearly 20 kilometers per second.

Astronomers will take the opportunity to study this asteroid, whose orbit around the sun lasts one years and seven months.

Not enough to fear a crash at the Don’t Look Up, the film released at the end of December on Netflix with Leonardo DiCaprio and Jennifer Lawrence in scientists that nobody listens to, therefore. It is estimated that a large asteroid crashes on average every 600,000 years on Earth, and NASA is designing a spacecraft that could deviate from its path if that happens.
