An SwRI-led study modeled the chemistry of TOI-270 d, a nearby exoplanet between Earth and Neptune in size, finding evidence ...

Exoplanets orbit stars outside of our solar system. Sub-Neptunes refer to planets between the size of our solar system's largest rocky planet, Earth, and the smallest gas giant, Neptune.
