The size and temperature of the star, as well as the orbit of the planet, largely determine the condition of having liquid water on the surface. This slide shows how dramatically different the planets in our solar system are in size. The 10 Most Earth-like Alien Planets: 10. TrES-3b has an orbital period of only 31 hours and is classified as a hot Jupiter for being large and close to its star, making it one of the easiest planets to detect by the transit method. Just a quick one today! This is a comparison of some interesting Exoplanets.Music: Stranger Danger by Francis Preve The TOI 700 is only 40% of Sun Mass and size and only half of its surface temperature. This is a list of exoplanets within the circumstellar habitable zone that are File:Exoplanet Size Comparison (Ft. Thanks to data from NASA’s Transiting Exoplanet Survey Satellite (TESS), an international collaboration of astronomers has identified four exoplanets, worlds beyond our solar system, orbiting a pair of related young stars called TOI 2076 and TOI 1807. The smallest exoplanet ever discovered is Kepler-37b. The orbital distance between the exoplanet and its host star does not affect the transit depth due to the enormous distance from Earth. Exoplanets with known masses and radii (red circles) are plotted along with solid lines that show the theoretical size of pure iron, rock, water, and hydrogen planets with increasing mass. NASA/Ames/JPL-Caltech The trouble with super-Earths.
