exomoon

• Variation in this time is not a smoking gun for an exomoon, because it has a number of possible causes, including another planet in the system. —  dailyindia.com News Feed
• And compared to the multitude of giant planets found thus far, an Earth-mass exomoon in the habitable zone would seem to offer a far more benign environment for life. —  Centauri Dreams
• The transit timing variation (TTV) signal varies according to both the mass of the exomoon and its orbital separation from the planet it circles. —  Centauri Dreams
• It becomes impossible using transit timing variations alone to determine the mass of the exomoon without plugging in some value for its orbital separation. —  Centauri Dreams
• An Earth-mass exomoon around such a world would be an achievable target. —  Centauri Dreams
