Earlier this year, astronomers found a minimoon orbiting Earth. It has now drifted away, but we should soon be able to detect more of these miniature companions. When astronomers at the Catalina Sky Survey in Arizona spotted a dim object called 2020 CD3 hurtling across the sky in February, they couldn’t be sure if it was a minimoon or an artificial object like a rocket booster. Over the following few months, Grigori Fedorets at Queen’s University Belfast in the UK and his colleagues used a series of telescopes around the world to take more measurements of the object and figure out what it was. They found that it had a diameter of about 1.2 metres. Based on its colour and brightness, it was probably made of silicate rock, like many rocks in the asteroid belt. The researchers also traced back its orbit in an effort to find out where it might have come from before it was caught in Earth’s orbit about 2.7 years earlier.

pamz: Is this a good place to put a question??? This board seems to have been well organized and energetic. What's happened? I know message boards can lose energy...is that it? Or, was it something else? Did the furious finger of GAWD strike you?
