First exomoon candidate!

Exoplanet Kepler-1625 b is a gas giant orbiting a G-type star in a relatively wide 287.38 days-long orbit. It was confirmed in 2016. Recently the HEK project (Hunt for Exomoons with Kepler) reported a new discovery - first significant exomoon candidate, orbiting this planet. Despite on only 3 transits that was observed, the exomoon signal could be clearly seen on the light curve, blending with the parent planet's signal:

Calculation shows that moon is a Neptune-sized body (!) separated by a 19 planetary radii from its parent planet. Uncertainty in the radius of the parent star is high (some recent works increased it 2 times compared to 2016 data), so both planet and moon could have significantly different radius than provided. But the parent planet's mass was derived from photometry, and being approximately 10 Jupeter's masses. This increases probability of existence of such a large moon.

The next transit of this system is expected in October 2017, and the team requested the time on the Hubble Space Telescope.

It's working with SE 0.9.7.3 :) Unfortunately i can't test on SE 0.9.8.0 due to my computer too old, lack of RAM and crashes blue screen of death

Nice and congrulations for people discover the first exomoon.
Maybe we will found a Terra (exo)moon breathable or/and the first (exo)moon orbit a (exo)moon orbit the planet...

Something we've been hoping to see for a long time.  Looking forward to the data from the next transit. :)

That moon is huge... it may be a binary planet system

Space engineer thare are more Exomoon are way before Kepler-1625b I It call 16 Cygni B I it is a Temperate Terra With Life organic multcellular marine terrestrial                                                                                                                                                       \                                   Image

I just saw this for the first time, sorry, is this add-on already in .980e?  And if not, which folder should it be put in?  Just the add-on folder or one of its subfolders?  Thanks!

Yes it is.
