How to detect exomoons?
Though exomoons are difficult to detect and confirm using current techniques, observations from missions such as Kepler have observed a number of candidates, including some that may be habitats for extraterrestrial life and one that may be a rogue planet. To date there are no confirmed exomoon detections.
What is the biggest exomoon?
The large gas giant is approximately the same radius as Jupiter and orbits its star every 287.4 days. In 2017, hints of a Neptune-sized exomoon in orbit of the planet was found using photometric observations collected by the Kepler Mission….Kepler-1625b.

| Mean radius | 11.4±1.6 R Earth |
| Mass | ≤11.60 M J |
How many exomoons have been discovered?
Bottom line: Astronomers examining data from the Kepler Space Telescope appear to have discovered six more exomoons.
When was the first exomoon discovered?
Kepler 1625b I
Kepler 1625b I, a possible moon of exoplanet Kepler-1625b, may be the first exomoon ever discovered (pending confirmation), and was first indicated after preliminary observations by the Kepler Space Telescope.
What is the best method to find Earth like planets?
transit method
The most successful search method used to date is called the transit method. If a planet passes directly between a star and the observer, it blocks out a tiny portion of the star’s light.
What is the largest exoplanet?
The widest known exoplanet, HAT-P-67 b, is a gas giant spanning twice the diameter of Jupiter, but it orbits so closely to its star that its year lasts less than five Earth days. The largest planet discovered to date, that astronomers are sure is a planet and has an accurately measured diameter, is HAT-P-67 b.
Can moons be habitable?
A habitable exomoon is a moon orbiting an extrasolar planet that has the ideal conditions to host life as we know it. A total of 21 exomoon candidates have been detected, but none of them have been confirmed. Beyond that, tidal heating might play a role for a moon’s habitability.
Can moons have satellites?
Yes, the Moon could have a sub-satellite. If we look at a system of the Earth, Moon, and a sub-satellite, the same idea as above applies. The Moon has its own Hill sphere with a radius of 60,000 km (about one sixth of the distance between the Earth and Moon) where a sub-satellite could exist.
How big is Kepler 1625?
Its mass is within 5% of that of the Sun, but its radius is approximately 70% larger reflecting its more evolved state….Kepler-1625.

How do scientists find planets?
By measuring the stars’ light emissions and observing how much light the transiting planets absorb, they will be able to make detailed inferences about planets’ masses, densities, and atmospheric compositions. This includes the potential to observe water and other key molecules known to support life.
What is a research proposal for an application?
Research proposal examples and advice for writing your own Your research proposal is an important part of the application process. It summarises the question you want to answer through your research. It demonstrates your knowledge of the subject area and shows the methods you want to use to complete your research.
How can I make my research proposal stand out?
Research Proposals Make You: OUTLINE steps in your proposed research THINK through your experiments Be CREATIVE (and you can use parts of it in your FINAL PAPER) JUSTIFY your research Provide Intellectual CONTEXT Anticipate a realistic TIMETABLE Anticipate Potential PROBLEMS.
Are there any exomoon detections?
To date there are no confirmed exomoon detections. Nevertheless, in September 2019, astronomers reported that the observed dimmings of Tabby’s Star may have been produced by fragments resulting from the disruption of an orphaned exomoon.
What is the habitability of an exomoon?
Habitability. Like an exoplanet, an exomoon can potentially become tidally locked to its primary. However, since the exomoon’s primary is an exoplanet, it would continue to rotate relative to its star after becoming tidally locked, and thus would still experience a day/night cycle indefinitely.
