For the first time, astronomers have discovered what could be an ‘exomoon’, a moon outside the Solar System.
Have Scientists Found FIRST Moon Outside The Solar System?Astronomers for the first time in history have discovered what could be an ‘exomoon’, a moon outside the Solar System.
The ‘exomoon’, which was discovered in orbit around a gargantuan gas planet 8,000 light-years from the Earth, is estimated to be the magnitude of Neptune.
It was identified in the data from NASA’s Kepler spacecraft and later detected using the Hubble telescope.
The Moon is thought to have formed about 4.51 billion years ago, not long after Earth. The most broadly known explanation is that the Moon formed from the debris left over after a giant impact between Earth and a Mars-sized body called Theia.
The Moon was first reached in 1959 by an unmanned spacecraft of the Soviet Union’s Luna program.
