A WHOPPING five asteroids will skim past Earth tomorrow, according to Nasa.
The space agency is calling the largest one 2019 TM7 and it’s estimated to be about the same size as Big Ben.
Asteroid 2019 TM7 could be anywhere between 138 to 312 feet.
That’s practically the same size as the Elizabeth Tower, commonly referred to as Big Ben, which measures in at 320 feet.
The large space rock will come within 2.5million miles from Earth and will pass us at around 14:41 BST tomorrow.
Any fast moving space object that comes within around 4.65 million miles is considered to be “potentially hazardous” by cautious space organisations.
Therefore, Nasa regards this as a “close approach”.
The asteroid is five times bigger than the Chelyabinsk meteor, which exploded over Russia back in 2013.
Its impact smashed windows and injured more than 1,000 people.
Experts did not predict the impact, sparking concern that Earth could be surprised with a more devastating incident in the future.
The other four asteroids are called 2019 TE2, 2019 TW6, 2019 TP5 and 2019 TA1.
Their sizes range from 31 metres to 59 metres in diameter.
The closest of the five approaches is predicted at 1.9million miles so there should be no need to panic.
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)

Designs for the ‘first space hotel’ have been revealed and it’s as weird and futuristic as you would expect.
And, the race for the world’s first ‘space birth’ is now underway and could happen by 2031, according to experts.
