Earth will get its very own ‘mini-moon’ which will remain in orbit for two months later this year.
From late September until late November this year, a “mini-moon”, called 2024 PT5 by the astrologers who spotted it approaching will be orbiting the planet. Although this mini-moon cannot be seen by the naked eye – it is just 10 metres (33ft) in diameter – it can be viewed through a high-powered telescope.
Mini-moons are asteroids which have been pulled by the Earth’s gravity into orbit around the planet and remain there until they become dislodged and move away again. The length of time these mini-moons remain in orbit depends on the speed and trajectory with which they approach the Earth.
Most mini-moons that enter Earth’s orbit are hard to see because they are too small and not bright enough to be seen against the backdrop of the darkness of space.
What, exactly, is a mini-moon?
