2024 PT5 is a near-Earth object roughly 11 meters (36 ft) in diameter discovered by ATLAS South Africa, Sutherland on 7 August 2024, the day before approaching Earth at 568,500 km (353,200 mi). [3] The object orbits the Sun but makes slow close approaches to the Earth–Moon system.

2024 PT5来自阿周那型小行星带，这是一个由太空岩石组成的次级小行星带，其轨道与地球非常相似，与太阳的平均距离约为1.5亿公里。 能成为“迷你月球”的天体通常在大约450万公里的近距离接近地球，并以大约每小时3540公里的速度“缓慢”飞行。 而阿周那型小行星带中的一些天体满足此条件，所以会暂时被地球的引力捕获。 [1] 2024年11月25日，2024 PT5已离开 地球轨道，再次回到以太阳为中心的轨道。 [3] 2024 PT5是一颗直径约11米的小行星，来自阿周那型小行星带。 …

2024年9月27日 · Despite the telescope’s bleak name, the moonlet PT 5 will not actually impact Earth — and won’t even orbit Earth entirely. Instead, it will take a horseshoe-shaped path around our planet...

2024年9月19日 · With this close approach to Earth, two asteroid scientists from Spain published a study in the Research Notes of the AAS suggesting that 2024 PT 5 would become a mini-moon from September 29 until ...

2024年10月2日 · Part of NASA’s Deep Space Network, the Goldstone Solar System Radar, near Barstow in California, will track the object during its next close pass of our planet, in January 2025, which will still be five times as far from Earth as the Moon. The asteroid will then leave the vicinity of Earth as it continues its orbit around the Sun.

2024年9月27日 · Starting Sept. 29, the Earth will have a temporary second “mini moon.” A new asteroid, named 2024 PT5, is set to briefly orbit the planet, marking a rare celestial event. Discovered in August, this asteroid is notable for its size and temporary orbital presence with the earth, earning it the informal title of a "mini moon."

2024年9月19日 · During its 56-day orbit, Asteroid 2024 PT5 will travel in a horseshoe-shaped trajectory before leaving Earth's gravity. It's unlikely we can catch a glimpse of the passing mini-moon as it enters...

2024年9月29日 · Called "2024 PT5" it is just about ten meters in diameter and it will remain in the Earth's orbit for about 53 days before heading back into the vastness of the solar system. Its size, though,...
