The "exoplanets" known as "Hot Jupiters".
Hydrogen and Helium
The Terrestrial planets have a higher density. Their structure includes a large percentage of rock, while the Jovian planets are composed mostly of gas.
Planets which began in dense matter regions have greater mass, and are able to hold onto their large, deep atmospheres of light gases like hydrogen and helium. (Jupiter's diameter is mostly atmosphere, while Earth's atmosphere is relatively shallow at about 1% of its diameter.)
The large planets of the Solar system are Jupiter, Saturn, Neptune and Uranus. They are considered gas giants because they consist mostly of gas with no solid surface.
Dependant on how the debris from supernovae is moving, the proportions of certain materials present, and the initial conditions of solar systems forming different combinations of terrestrial and Jovian planets are formed. Terrestrial planets are comprised of heavier particles (ie. of higher relative atomic mass) meaning they have stronger gravity which leads to higher density planets than the gaseous Jovian planets. A Jovian planet can be thought of as a failed star - it has all the elements needed to fuel nuclear fusion, but not enough gravity to attain the nuclear activation energy required. So the Sun started as a large cloud mostly comprising of gases, and terrestrial planets were formed from clouds mostly consisting of heavy solids.
They are very large, and consist of mostly gases.
well its your mom and dad
The exoplanets called "Hot Jupiters."
No planet is made of glass, as far as I know. The giant planets - Jupiter, Saturn, Uranus, Neptune - are large, and made mostly of gas. However, they are not fast-moving.The inner planets - Mercury, Venus, Earth, Mars - are slow, fast-moving, and made basically of rock.
the sun is a very large gasious fire ball,if the gases dont move the sun will exploade and burn earth and some other planets to a crisp.:)
No, those are the outer planets.
The difference between large planets and small planets are that large planets are made up of gases and therefore don't have soild surfaces where as small planets are made up of rocks and other materials liek that and have soild surfaces.
Hydrogen and Helium
Jupiter
No its a small planet. It has a radius of 2439 km or 1515 miles. Its not made of gas...its a rocky planet made of mostly iron. Planets that do fit your description are Jupiter, Saturn, Neptune and Uranus.
The large planets in our solar system are composed mainly of gases, as is the Sun. They have dense, gaseous atmospheres around a smaller core. Uranus and Neptune have a higher percentage of methane, ammonia and water than Saturn and Jupiter, which are mostly hydrogen and helium.
large planets are called the outer planets or the JOVIAN PLANETS which are made up of gases and viscous liquids... terrestrial planets are the inner planets! inner planets- MERCURY VENUS EARTH MARS outer planets- JUPITER SATURN URANUS NEPTUNE
