Mars is the second smallest with a diameter of 6792km (this is assuming that the dwarf planet Pluto, which has a diameter of 2390km, is not considered; if it is considered, then Mars would be the third smallest). Mercury is the smallest, with a diameter of 4879km.

Mercury is the smallest actual planet of the eight comprising the solar system. It is actually smaller (but more massive) than the moons Ganymede and Titan. Mercury has about 5.5% of the mass of Earth.Before 24 August 2006, Pluto considered the smallest planet of our solar system. On that date, the IAU modified the definition of "planet" and Pluto no longer qualified. It was reclassified as a "dwarf planet." There are a number of smaller objects, including dwarf planets, asteroids, and Kuiper Belt objects (past the orbit of Neptune).Sizes of the Planets (largest to smallest)JupiterSaturnUranus (3rd largest)Neptune (3rd most massive)EarthVenusMarsMercury

Not counting Pluto, 4th largest. Funny how you phrase it "your solar system"
it is the smallest
Uranus is the third largest planet in our Solar System, with a diameter of 51,118 km. The largest and second largest planets are Jupiter and Saturn, respectively. The smallest planet is Mercury.
Mars is the second smallest with a diameter of 6792km (this is assuming that the dwarf planet Pluto, which has a diameter of 2390km, is not considered; if it is considered, then Mars would be the third smallest). Mercury is the smallest, with a diameter of 4879km.

None of the above. Earth is the 4th smallest planet.
No. It is the smallest of all.
Satun is the 2nd largest planet
Jupiter is the largest planet in our solar system.
Mercury is the smallest planet and Mars is the next after that. It's the 2nd smallest planet. There are 8 planets. So, Mars is also the 7th largest planet in the solar system.
