భూమికి రెండవ చంద్రుడు, అద్భుతాన్ని కనుగొన్న శాస్త్రవేత్తలు
The Minor Planet Centre has just announced that the Earth has been orbited by a second moon for the past three years or so. But while excitement about the discovery is growing, it is important to keep in mind that this moon isn’t as impressive as our main satellite. It is extremely faint – it is estimated to be only between one and six metres across – and won’t be with us for much longer.
The body was first spotted by US astronomers Theodore Pruyne and Kacper Wierzchos using a 1.52-metre (60 inches) telescope at Mount Lemmon Observatory near Tuscon, Arizona on February 15.
Subsequent observations enabled its orbit to be calculated, and at 22:53 Universal Time (UT) on February 25, the Minor Planet Center announced the discovery, designating it as 2020 CD₃ and confirming that it is temporarily bound to the Earth.
