HIGHLIGHTS 

Exolpanet 'Kepler 1708b' is at the centre of the new object.

Earth is 5,500 light-years distant from of the exoplanet.

NASA's Kepler space telescope was used to find it.

WHY IN NEWS

Scientists have identified over 10,000 exoplanets, or planets outside our solar system, but they have yet to find a moon circling any of them — at least not yet. They have presented a discovery in a recent research that they believe might change this. The celestial body discovered might be a large moon circling a planet outside the solar system, according to researchers. The moon circles a Jupiter-sized exoplanet, and if the preliminary findings are verified, it might be the first 'exomoon.'

Another possibility for exomoon was discovered four years ago, but confirmation is still pending. Many people are concerned that the new contender will suffer the same fate. Both candidates have many similarities, such as orbiting comparable planets, although the latest one is a little smaller. Both of these objects are thought to be comprised of gas and might have formerly been planets in their own right before being pushed into the orbits of larger worlds.

According to a research published in the journal Nature Astronomy, the new object revolves around Kepler 1708b, an exoplanet 5,500 light-years from Earth. Scientists examined 70 gas giants using NASA's Kepler satellite observatory and identified just one candidate that seemed to be an exomoon. This contender is around 2.6 times the size of Earth. Researchers are encouraged by the new finding and feel that there are likely to be more moons on faraway worlds that are comparable to our own. 'The weirdos will typically be the first detections in any survey,' David Kipping, who conducted the study on both new and older exomoon possibilities, told the Independent. 'With our limited sensitivity, the huge ones are just the simplest to spot.'

Because both moon possibilities are distant from their host star, they are less likely to be yanked off of their orbits.
