We may not have enough information yet to answer this question, since we don't have substantial geological knowledge of all the planets. According to the current understanding, they were all being formed about the same time. The immense disk of materials that formed around the sun, the accretion disk (a little like the rings of Saturn) was condensing into planets more or less simultaneously.
There are a few steps of a solar system project. You first have to study the solar system.
The first planet in the solar system is Mercury
Nothing man-made has left our solar system yet. The furthest thing is Voyager 1, which is now about 116AU away from Earth, around 10.8 billion miles - at the edge of our solar system.
Mercury,Venus,and Earth. that's for our solar system.
A first generation solar system would have contained mostly hydrogen and very little if any of the heavier elements. Second generation solar systems, made from the exploded remnants of first generation stars, would have a higher proportion of heavy elements and thus have more rocky planets and stars that could use energy sources other than hydrogen fusion after their hydrogen was exhausted.
The sun is the first and only star in the solar system.
mecury is first in the solar system

Not in my solar system.
CERES is the first and the biggest asteroids in the solar system
That depends on what definition of first you mean. A solar system is in a galaxy and a galaxy is in space. So the solar system is smallest and space is largest.
The first planet closest to the sun in our solar system is Mercury.

As soon as there was a solar system.
The first planet in the solar system is Mercury
If we are talking about being off the Earth and in the solar system Yuri Gagarin.
The current model of the solar system was first conceived by Nicolaus Copernicus, but the idea of a heliocentric solar system was known to the Greeks of antiquity.
