According to Oklahoma Edition of McDougal Littell Science Grade 7 the Terrestrial Planet that has the oldest least changing surface is Mercury. Mars has wind that carries sand that changes its surface. Venus has volcanoes and tectonic plates that change its surface. We know that Earth has erosion, volcanoes and tectonic plates that change the surface. This leaves Mercury.
Mercury is believed to have the oldest surface among terrestrial planets in our solar system. Its surface is heavily cratered, indicating that it has not undergone significant geological changes for billions of years.
All the planets are roughly the same age. We would have to visit each planet and study it to find out which is actually the oldest.

The oldest lunar features are called lunar highlands. These are areas on the Moon's surface that are heavily cratered and have not experienced significant volcanic activity, making them some of the oldest regions on the Moon.
The Sun isn't a planet, it's a star. Without having energy from the Sun there can be no life on any planet. It is incorrect to say that the Sun was the "first or oldest planet" because it is most likely that the planets were formed during the same era of time as when the Sun itself was created.

Because Mercury is nearest to the sun, which gives more heat and gravitational pull. It is also the smallest and second-densest and has the greatest day and night temperature variations. It also has the oldest surface. Besides earth, it is the only terrestrial (rock like; not a gas planet) planet that has a global internal magnetic field.
The oldest dwarf planet is Ceres. See related links for more information.

The oldest terrestrial insect fossils are found in rocks dating back to the Devonian Period, approximately 400 million years ago. These fossils provide insight into the early evolution and diversification of insects on land.
