Jupiter – The largest planet, its dark red spot is a storm larger than Earth. It's conceivable that a rocky planet with a radius three times that of the Earth could exists under such conditions, but such planets are probably quite rare. The next largest of the Kepler-37 planets is also smaller than the Earth, while the third is more than twice Earth’s size. With our cookie Policy masses close to its star 's habitable zone size limit for smaller rocky exoplanets amount orbital. Due to their size and proximity to Kepler-444, these must be rocky planets, with masses close to that of Mars. Well, the largest known rocky planet is the Earth, but I don't think anyone knows the theoretical upper limit, because there are so many variables. “If confirmed to be rocky, the composition of BD+20594b would be unprecedented for exoplanets of this size,” the authors note in their paper on Arxiv.

This is probably a rocky world with about 5 Earth masses and 1.5 times our planet's radius. Some caution is needed, though; the researchers noted that further studies will be needed to confirm its rocky composition, especially as it is at the hotly debated boundary between terrestrial planets and gas giants. The University researchers deemed that Planet TOI-849b can be considered a hot Neptune, but its at least twice as massive as Neptune.

The new planet is about 16 times as massive as Earth and half the diameter of Neptune. They are made of rocks and metals. The authors came to the conclusion that the planet is likely rocky because of its mass-to-radius ratio, from which its density can be calculated: 8 grams per cubic centimeter, compared to 5.5 for Earth.

A super-Earth is an extrasolar planet with a mass higher than Earth's, but substantially below those of the Solar System's ice giants, Uranus and Neptune, which are 14.5 and 17 times Earth's, respectively. The two outer planets (Poltergeist and Phobetor) of the system have masses approximately four times Earth—too small to be gas giants. With a mass of only 14 times the mass of the Earth, the new planet lies at the threshold of the largest possible rocky planets, making it a possible super Earth-like object.

Its atmosphere is composed of gasses mainly hydrogen and helium. The 'ideal' case for a large rocky planet is for it to be close to a highly luminous star, so that the star's light and radiation blow away any atmosphere from the planet. Intense UV radiation from red dwarf stars was thought to make potentially habitable exoplanets unable to support life. Luckily, the planet’s host star is exceptionally bright, allowing a more detailed observation than most exoplanets. It is so gigantic that all other planets in the solar system could fit into Jupiter. The smaller, inner planets include Mercury, Venus, Earth, and Mars.
