Pluto used to be the smallest planet, but it's not a planet any more! That makes Mercury the smallest planet in our Solar System. The second smallest planet in the Solar System is now Mars, measuring 6792 km across.
The smallest planet in the solar System is Mercury the biggest planet is Jupiter For the longest time, the smallest planet was considered to be Pluto, but now Pluto isn't a planet any more, so we're back to Mercury.
Actually Neptune is between the smallest and the largest planet. Because Pluto has been a dwarf planet. The size order of the planets are (from smallest to largest) 1 mercury, 2 mars, 3 Venus, 4 earth, 5 Neptune, 6 Uranus, 7 Saturn and 8 Jupiter.
Earth is 1 AU from the Sun. There is no planet at an orbit of 2.5 AU. (Mars orbits at 1.5 AU and Jupiter at 5.2 AU).
Viking 1 landed on Mars in July 1976.

Of the inner rocky planets, Mars is the second smallest, coming just a little bit smaller than Venus and Earth. When all eight planets are considered, Mars ranks seventh in size.

-1 = biggest-11 = smallest
Bear in mind that Pluto has been reclassified as a dwarf planet. Venus ranks as planet #3, being larger than Mercury and Mars, but smaller than Earth.
Jupiter is the biggest, Saturn is the second biggest.
