Mid-Jupiter

Mid-Jupiter, also known coincidally as jovian planet, is a classification of with mass ranging from 0.5 to 2 es or 158.9 to 635. es. Mid-Jupiters are with no solid surface. Hence it is the second most massive mass class of planet, mid-Jupiter is rated M-Class II and has the symbol Jb.

Characteristics
Mid-Jupiters are with no solid surface, but there is a rocky core surrounded by liquid hydrogen-helium mixtures in upper mantles and liquid metallic H-He in lower mantles. Those planets have banded clouds with several featured storms powered by interiors or sunlight depending on the planet's distance from the star. Mid-Jupiters have radii ranging from 0.8 R$J$ to 1.4 R$J$. s are larger, up to 2 R$J$, caused by intense heating from nearby stars causing.

Abundance
There are an estimated 69 billion mid-Jupiters in alone, making it the second least abundant mass class of planet after super-Jupiter. This corresponds that 84‰ of all 820 billion planets in our galaxy are mid-Jupiters.

Known mid-Jupiters
, the only mid-Jupiter in our solar system, and more than 300 around other stars are mid-Jupiters. The first planet found around an ordinary star, (Bellerophon), is a mid-Jupiter. Few other notable exoplanets are mid-Jupiter as well: (Osiris), ( (Teumesia), and, (Tapio). Tapio, the only solid mid-Jupiter known, is an ultra-dense  that orbits around the pulsar. However Tapio was a  in the past that lost more than 99.9% of its original mass because of the proximity to its parent  causing.
