A huge asteroid classed by NASA as "potentially hazardous" is set to pass Earth later this week.
The space rock, which could be as big as 260m according to expert, will pass Earth at safe distance traveling at nearly 30,000mph.
NASA have named the rock Asteroid 2020 ND, and think it will shoot past us on July 24.
It isn't the first time it has visited our planet either, with space researchers saying it has passed us by at least five times that we know about.
Estimated to be between 120m and 260m in diameter, it may well be bigger than Arthur's Seat, which stands at 251m.
It has been listed as a potential hazard, with the space agency explaining what this means, according to Birmingham Live : “Potentially Hazardous Asteroids (PHAs) are currently defined based on parameters that measure the asteroid’s potential to make threatening close approaches to the Earth.
“Specifically, all asteroids with a minimum orbit intersection distance (MOID) of 0.05 au or less are considered PHAs.”
Earlier this month, another asteroid bigger than the Tron Kirk came closer to the Earth than the Moon.
It was thought to have passed us by at the equivalent of 44,618 miles, closer than the Moon which is some 238,855 miles away from us.
We also reported in June how another rock at least 250m tall was due to pass Earth. According to SpaceReference.com, that one was larger than 90% of all others.

This and other asteroids are tracked constantly by NASA alongside the European Space Agency to monitor any risk they might pose to Earth.
Space events aren't uncommon, and whilst this rock is listed as potentially hazardous scientists say it remains unlikely that Earth is at threat from any of the many Near Earth Objects currently being tracked.
