Natural satellites (extrasolar) constitute a research area focused on the detection, characterization, and theoretical modeling of moons orbiting exoplanets outside the Solar System. This field investigates formation pathways (e.g., co-accretion, capture, giant impacts), dynamical stability, tidal evolution, and potential habitability of exomoons, as well as their influence on planetary system architectures and observable signatures. Research emphasizes indirect detection techniques, including transit timing and duration variations, transit light-curve anomalies, and high-precision photometry and spectroscopy. It also explores population statistics, mass–radius distributions, and atmospheric and surface properties, integrating numerical simulations, analytic dynamics, and upcoming observational capabilities from space- and ground-based facilities.
The moon has played a huge role in the development of Earth. It stabilizes the planet, tempers dramatic climate swings, and possibly even provides the tidal heating that might have led to the first life forms. So it's natural ...

Provided they host thick, hydrogen-dominated atmospheres, moons orbiting free-floating exoplanets could retain much of the heat generated deep within their interiors by tidal forces. Led by David Dahlbüdding at the Max Planck ...
Our solar system hosts almost 900 known moons; more than 400 orbit the eight planets while the remaining orbit dwarf planets, asteroids, and Trans-Neptunian Objects (TNOs). Of these, only a handful are targets for astrobiology ...

Free-floating planets, or as they are more commonly known, rogue planets, wander interstellar space completely alone. Saying there might be a lot of them is a bit of an understatement. Recent estimates put the number of rogue ...

So far, humanity has yet to find its first "exomoon"—a moon orbiting a planet outside of the solar system. But that hasn't been for lack of trying. According to a new paper by Thomas Winterhalder of the European Southern ...

Forty light-years away, seven Earth-sized planets orbit around a dim red dwarf star in one of the most tightly packed planetary systems ever discovered. The TRAPPIST-1 system has captivated astronomers since 2017, with three ...

Searching for exomoons—moons that orbit around another planet—was one of the most exciting capabilities expected of the James Webb Space Telescope (JWST) when it launched in late 2021. So, after four years of operation, why ...

At a young age, we're told how the sun warms Earth and makes life possible. That idea sticks with most of us for life. But when we want to understand things more thoroughly and we dig more deeply, we learn that Earth has ...

There are no confirmed exomoons, moons orbiting distant exoplanets in other solar systems. There are a few candidates, but none have passed the threshold and been accepted as confirmed. But they must exist. Moons are common ...
