To locate the free-floating planet, a team of international astronomers led by those from the University of Warsaw’s OGLE team at the Astronomical Observatory used an astronomical phenomenon called gravitational microlensing.
The object called 2020 CD3 and measuring just a few metres in diameter, entered Earth's orbit about three years ago. The ‘mini-moon’ circles the Earth every 47 days but is slipping from Earth’s gravitational pull and in few months will leave us.
The technology can aid emergency services fighting forest fires when normal satellite images are obscured by smoke.
Named by the Polish astronomers who found them, the planets could be just two of millions floating through the galaxy. So far, though, scientists have only managed to locate a dozen or so rogues, which is why adding these two to the bunch is deemed important.
Dziewanna, which was discovered by Polish scientists at Warsaw Uni, is estimated to be 470 kilometres across, making its surface one-seventh of the Moon’s and one of the 40 largest known objects in the Solar System.
