Exoplanet satellite or giant celestial body detection around the planet - Second exomoon candidate
地球から５５００光年離れた木星サイズの惑星「ケプラー１７０８ｂ」の周回軌道で、衛星の可能性がある巨大天体が検出されたことが分かりました
It was found that a giant object that could be a satellite was detected in the orbit of the Jupiter-sized planet ”Kepler 1708b”, which is 5500 light-years away from the earth.
This is the second discovery of a celestial body that is a candidate for an exoplanet.
この発見について詳述した論文は１３日の科学誌ネイチャー・アストロノミーに発表されました
A paper detailing this discovery was published in the scientific journal Nature Astronomy on the 13th.
新たに検出された天体は地球の２．６倍の大きさを持ちます
The newly detected celestial body is 2.6 times larger than the Earth.
これまでに４０００個あまりの系外惑星が確認されていますが、発見は簡単ではありませんでした
About 4000 exoplanets have been confirmed so far, but it was not easy to discover.
Many exoplanets are detected by the ”transit method”, which looks for dimming as the planet crosses in front of the star.
Satellites are smaller than planets and have less dimming, making them even more difficult to discover.
