4953 (1990 MU) is a mid-sized asteroid whose orbit crosses the orbit of Earth.
The IAU Minor Planet Center records 502 observations used to determine its orbit. Movies tell us they would keep it secret.
For reference, Mars – the planet which humans are hoping to reach – is around 0.5 AU.The asteroid is classed as a potentially hazardous asteroid, which according to According to data from NASA, 2019 OK was large – an estimated 187 to 427 ft (57 to 130) wide – and hurtling fast along a path bringing it within only 45,000 miles (73,000km) of Earth when it flew by in recent weeks.This was less than one-fifth of the distance to the Moon and what the Royal Institution of Australia’s Professor Alan Duffy described as “uncomfortably close.”That asteroid would have been big enough to wipe out a city, so 1990 MU could be truly devastating.Asteroid 1990 MU is up to nine kilometres in diameter, which puts it in the same ball-park as the space rock which put an end to the dinosaurs.Research from the University of Glasgow has found up to three quarters of life on Earth was wiped out from the asteroid, with the dinosaurs dying out within a few centuries.The space rock caused a cloud of dust to fill the air which blocked out the sun, leading to drastic and sudden climate change that ultimately created major food shortages across Earth, leading to the death of bigger animals, and allowing smaller creatures, such as mammals, to thrive in their absence.While the asteroid will be close within the next decade, it will be even closer in 2058, when it comes within 0.02 AU - less than three million kilometres.Scientists estimate that a life-ending asteroid, such as the one which put an end to the dinosaur’s reign, would collide with Earth every 100 million years or so.But asteroids can strike at any moment and there is always a very slim chance a massive civilisation-ending space rock could hit sooner.For that reason, many claim global authorities should have a plan in place – but it seems they do not.NASA employee Robert Frost, who works as an instructor and flight controller for the space agency according to his bio on Q+A website Quora, said the best thing governments could do is tell the public to “hunker down”, as there would be little which can be done to prepare for the inevitable.Mr Frost was writing in response to the question: “If it were discovered that an asteroid was going to wipe humanity out, say in 2 months, how would the governments of the world respond?”He said: “That’s a tough one.
At approximately 3 km in diameter, it is one of the largest known ECAs. (4953) 1990 MU is a large Earth-crossing asteroid (ECA) belonging to the Apollo family of asteroids which also cross the orbits of Mars and Venus. But, there are a handful of near-Earth objects in the space which can be potentially dangerous for the Earth. RELATED: Newly found planet close to … A huge asteroid which is classified to be as big as the one which hit the Earth millions of years ago and led to the extinction of the dinosaurs is feared to come dangerously close to our planet in the coming decade. 4953 (1990 MU) is a mid-sized asteroid whose orbit crosses the orbit of Earth. The 1990 MU asteroid is estimated to be around 4-9 kilometres in diameter, which puts it in the same category as the space rock which brought an end to dinosaurs the … 1990 MU's orbit is determined by observations dating back to July 21, 1974. This means that there is an wide berth between this asteroid and Earth at all times. 1990 MU's orbit is 0.03 AU from Earth's orbit at its closest point. The asteroid known as 1990 MU is currently completing another orbit of the Sun, and in 2027 it could come perilously close to Earth. The giant asteroid, which has a diameter of 4-9 kilometres, will be close to our planet precisely on June 6, 2027, reported Express.co.uk.
