(Phys.org)—A team led by David Kipping of Columbia University has spotted what might be the first evidence of an exomoon. They have written a paper describing their findings and have uploaded it to the arXiv preprint server.
An exomoon is a moon orbiting an exoplanet. Many moons have been found in our solar system and many planets outside of it, but to date, no one has captured evidence of a moon orbiting one of those exoplanets. This might change, as the team studying data from the Kepler Space Telescope believe they have found strong evidence for a moon orbiting a planet which is itself orbiting a star called Kepler-1625.

Exoplanets are found by noting the dimming of stars that occurs as a planet passes between Earth and the star. A moon would be found in roughly the same way, the researchers note, by looking for dimming that occurs in the light reflected from a planet caused by the transit of a moon. Kipping and his team report that they recorded three such dippings as the planet made three trips around its star.

It seems by the definition, that our moon is an exomoon, along with the other planets in this system???? Right???
An exoplanet or extrasolar planet is a planet that orbits a star other than the Sun.
This systems orbits a start that orbits a larger star in the center....Am I getting this right?
I'm just trying to figure out why this is soo exciting?
