Gas, Menthane, Ice, Water, Ammonia, and Rock
Each outer planet is made up of gas
The inner core is a solid, and the outer core is a liquid.
The outer cores is made up of mostly iron and nickel in a liquid state.
I guess that would be Mars, which has an orbit outside the Earth's orbit. The first four planets have solid cores, while the four outer planets are gas giants.
-Subdivided into outer and inner cores -Outer core is made up of nickel-iron alloy -Inner core is made up entirely of iron
The cores of all four Jovian planets are made of rock, metal, and gasses. The difference between the planets are the layers that surround the cores.
A star and a planet, both have cores.
it is made up of gas and liquids.
The outer cores is made up of mostly iron and nickel in a liquid state.
Earth is an inner planet. The inner planets are Mercury, Venus, Earth, and Mars. The outer planets are Jupiter, Saturn, Uranus, and Neptune. The inner planets are warmer and have solid, rocky cores. The outer planets are much cooler, bigger and are mostly, if not entirely, gas.
Neptune doesn't have an outer core. The only core Neptune has is the molten inner core in the middle of the planet. Neptune is a gas giant, which means it does not have a solid surface.
You would have to be more specific: Your Term " Outer Planet " is very broad. If you are Asking about This Planet or Planets Beyond This one: you must say so. This is not Star Trek : Getting Out to Other Planets to Research is not easy and is still Going VERY slow.
