The space rock, officially called asteroid 231937 (designated 2001 FO32), will zoom past Earth on March 21 travelling at a speed of 123,887 kilometres per hour or 34.4 kilometres per second, according to NASA. The asteroid is an estimated 1.1 kilometres wide, which is roughly twice the size of the CN Tower.

How fast was the asteroid going?
The near-Earth asteroid, known as 2001 FO32, will be 1.25 million miles, or more than five times the distance between Earth and the moon, during its closest approach. It will also be moving much faster than most asteroids that fly by our planet, rocketing along at 77,000 miles per hour.
How fast is the fastest meteor?
The fastest move at about 42 km/s (94,000 mph) through space in the vicinity of Earth’s orbit. This is escape velocity from the Sun, equal to the square root of two times Earth’s speed, and is the upper speed limit of objects in the vicinity of Earth, unless they come from interstellar space.
What is the fastest thing in the universe?
Laser beams travel at the speed of light, more than 670 million miles per hour, making them the fastest thing in the universe.
How big was the asteroid that killed the dinosaurs?
It was tens of miles wide and forever changed history when it crashed into Earth about 66 million years ago. The Chicxulub impactor, as it’s known, was a plummeting asteroid or comet that left behind a crater off the coast of Mexico that spans 93 miles and goes 12 miles deep.
Is there an asteroid coming 2021?
Potentially hazardous asteroid discoveries
A list of near-Earth asteroids classified as potentially hazardous objects discovered in 2021. As of March 2021, 2021 AV7 is the largest potentially hazardous object discovered in 2021 so far.
Can we survive an asteroid?
The fact that humans are smarter than dinosaurs gives them an edge when it comes to surviving an asteroid impact. “So long as we retain at least stone age technology, there isn’t much that could make us extinct,” Robert Walker, a scientist and mathematician, told Science 2.0.
Is there an asteroid on the way April 2020?
On April 29, 2020, around its closest approach to Earth, asteroid (52768) 1998 OR2 will pass close to galaxy NGC 3463 and star HIP 53416.
When did the last asteroid hit Earth?
The last known impact of an object of 10 km (6 mi) or more in diameter was at the Cretaceous–Paleogene extinction event 66 million years ago. The energy released by an impactor depends on diameter, density, velocity, and angle.
How close is the asteroid coming to Earth?
The 3,000-foot-wide asteroid, the largest expected to come this close to Earth in 2021, will pass safely at an estimated 1.25 million miles away.
Has the asteroid passed Earth yet?
The largest of the three space rocks, a house-size asteroid called 2021 FH, passed by Earth today at approximately 12:52 p.m. EDT (1652 GMT) at a distance of roughly 145,940 miles (234,870 kilometers), or 0.61 times the average Earth-moon distance.
What is the fastest comet?
At a breathtaking speed of over 175 000 kilometres per hour, Borisov is one of the fastest comets ever seen. It is only the second interstellar object known to have passed through the Solar System. In October 2019, Hubble observed the comet at a distance of approximately 420 million kilometres from Earth.
Why is a comet called a comet?
The name comet comes from the Latin word cometa which means “long-haired”. The earliest known record of a comet sighting was made by an astrologer of the Chinese court in 1059 B.C. Scientists believe that comets are the debris left from the solar nebula which condensed to form the Sun and planets in our solar system.
What happen during a meteor shower?
Meteor showers occur when the earth in its orbit around the Sun passes through debris left over from the disintegration of comets. … When the earth intersects this orbit in its annual trip, it can run into this debris, which burns up on entry into the earth’s atmosphere, producing a visible shower of meteors.
