NASA has revealed it is closely tracking a whopping five asteroids due to skim past Earth tomorrow.
The space rocks, which have been flagged as potentially dangerous by Nasa, are zipping towards our planet at speeds of up to 50,000mph.

The largest, dubbed 2019 GN4, is an alarming 220 feet across – meaning it’s bigger than the Leaning Tower of Pisa.
GN4 will whip past our planet at around 10:20pm GMT on Saturday evening.
It follows the rogue objects GN (2:08am), GO4 (8:07am), F01 (2:52pm) and FH1 (3:03pm) on a roster of five close approaches on Saturday.
The quickest of the space rocks is GO4, which is currently hurtling through space at 50,000mph.

Travelling at this speed, you’d be able to rocket from Earth to the Moon in just five hours.
The good news is that asteroids regularly pass close to Earth, so there’s no need to panic.
In fact, Nasa has already designated 32 “near-Earth objects” as making a “close approach” during the month of April alone.
It’s also important to remember that a “close approach” might not be as close as you’d think.
The tightest of Sunday’s passes will come when GN comes within 400,000 miles of our planet.
What's the difference between an asteroid, meteor and comet?
Here's what you need to know, according to Nasa…
- Asteroid: An asteroid is a small rocky body that orbits the Sun. Most are found in the asteroid belt (between Mars and Jupiter) but they can be found anywhere (including in a path that can impact Earth)
- Meteoroid: When two asteroids hit each other, the small chunks that break off are called meteoroids
- Meteor: If a meteoroid enters the Earth’s atmosphere, it begins to vapourise and then becomes a meteor. On Earth, it’ll look like a streak of light in the sky, because the rock is burning up
- Meteorite: If a meteoroid doesn’t vapourise completely and survives the trip through Earth’s atmosphere, it can land on the Earth. At that point, it becomes a meteorite
- Comet: Like asteroids, a comet orbits the Sun. However rather than being made mostly of rock, a comet contains lots of ice and gas, which can result in amazing tails forming behind them (thanks to the ice and dust vapourising)
That’s relatively close in space terms, but is still nearly twice the distance between Earth and the moon.
And if it’s any consolation, Nasa doesn’t think we’ll be hit by a space rock any time soon.
The agency says: “Nasa knows of no asteroid or comet currently on a collision course with Earth, so the probability of a major collision is quite small.
“In fact, as best as we can tell, no large object is likely to strike the Earth any time in the next several hundred years.”
