From this article: “The largest “terrestrial” planet is generally considered the one before you get too thick of an atmosphere, which happens at about 5-10 Earth masses (something like 2 Earth radii). It used to be the largest rock of any type known until earlier last year. It was previously assumed that rocky planets could get no larger than 1.6 Earth radii, and this one would be half again … TON-618 has become a hot topic in the study of black holes in recent years as it sits as the most massive known in the universe. The larger the planet, the lower the average density, and there's a structural lower limit to the density. In terms of mass, Jupiter dwarfs the other planets. Me neither, not ever since the planet Pluto has been demoted from its status, to the position of minor planet. : An analysis of the lightcurve of the microlensing event PA-99-N2 suggests the presence of a planet orbiting a star in the Andromeda Galaxy (2.54 ± 0.11 Mly). In the solar system there are four terrestrial planets, two gas giants and two icy planets. An asteroid is a rocky body which lies in the asteroid belt between Mars and Jupiter. (Nobody knows for sure what size rocks lie at the cores of Jovian planets, or orbit other stars.) With two barren peaks that rise only about 170 feet above sea level, the now extinct Pūhāhonu volcano in the Northwestern Hawaii Islands doesn't look like much. The largest asteroid Ceres has been reclassified as a dwarf planet. More variety is hidden within these broad categories. Mars is a planet in the solar system and is the 4th closest planet to the sun. The bulky object—possibly the core of a failed gas giant—challenges what astronomers think about how planets form. The largest planet in our solar system by far is Jupiter, which beats out all the other planets in both mass and volume. CHEOPS is a joint mission by the European Space Agency (ESA) and Switzerland, under the aegis of the University of Bern in collaboration with the University of Geneva.

Largest planet in the universe. Earth is the largest terrestrial planet, the densest and most geologically active inner planet and the only body in the Solar System with significant liquid water on its surface. CHEOPS keeps its promise: Observations with the space telescope reveal details of the exoplanet WASP-189b – one of the most extreme planets known. The problem is the transition from "rocky" to "gas giant" is not well defined. Skip to comments. There's a new type of planet in our universe--and it's a big one. The exact size of the planet has been impossible to calculate, but due to comparisons of other nearby stars, we may have an idea.
