Oldest planet in solar system

Jupiter may be the solar system''s oldest planet

That would make Jupiter the oldest planet in the solar system. Its early existence would have created a gravitational barrier: That barrier would have kept the two rock neighborhoods segregated. Jupiter would then have continued growing at a slower rate for the next few billion years. The planet topped out at 317 times the mass of the Earth.

Solar System Exploration

Let''s look at the mean temperature of the Sun, and the planets in our solar system. The mean temperature is the average temperature over the surface of the rocky planets: Mercury, Venus, Earth, and Mars. Dwarf planet Pluto also has a solid surface.
