Mercury is the smallest planet in our solar system. Pluto might have been the smallest planet, but it has now been reclassified as a "dwarf planet." The smallest planet in our solar system now is Mercury. There might well be billions of smaller planets outside for solar system. The smallest exoplanet found so far is about twice the size of the Earth.

You might as well say, closest to the Earth, or to the Solar System - since distances within the Solar System are insignificant compared to the distances to other star systems.The closest star system is Toliman, also known as Rigil Kentaurus, or Alpha Centauri.The closest known galaxy is a dwarf galaxy, the Canis Maior Dwarf Galaxy - a satellite of our galaxy.You might as well say, closest to the Earth, or to the Solar System - since distances within the Solar System are insignificant compared to the distances to other star systems.The closest star system is Toliman, also known as Rigil Kentaurus, or Alpha Centauri.The closest known galaxy is a dwarf galaxy, the Canis Maior Dwarf Galaxy - a satellite of our galaxy.You might as well say, closest to the Earth, or to the Solar System - since distances within the Solar System are insignificant compared to the distances to other star systems.The closest star system is Toliman, also known as Rigil Kentaurus, or Alpha Centauri.The closest known galaxy is a dwarf galaxy, the Canis Maior Dwarf Galaxy - a satellite of our galaxy.You might as well say, closest to the Earth, or to the Solar System - since distances within the Solar System are insignificant compared to the distances to other star systems.The closest star system is Toliman, also known as Rigil Kentaurus, or Alpha Centauri.The closest known galaxy is a dwarf galaxy, the Canis Maior Dwarf Galaxy - a satellite of our galaxy.

The largest body in the asteroid belt is Ceres, with a diameter of about 950 km. Although it has long been considered to be an asteroid, Ceres was classified as a "dwarf planet" on August 24, 2006. (The other dwarf planets are Pluto, Makemake, Haumea, and Eris.) The issue of whether Ceres remains an asteroid was not addressed at that time.
Callisto is a moon of the planet Jupiter. It is the third largest moon in the Solar System and the second largest in the Jovian system, after Ganymede. Callisto has about 99% the diameter of the planet Mercury but only about a third of its mass. It's diameter is approximately 4820km - about a third of Earth. [See link for pictorial comparison]
Saturn's moon Titan is larger and Jupiter's moon Callisto is smaller.
Callisto orbits Jupiter at a distance of about 1,883,000 miles. It has a diameter of about 3000 miles, or 4800 kilometers.
Mercury is the planet closest to the Sun in terms of size. It is the smallest planet in our solar system, with a diameter of about 4,880 kilometers (3,032 miles).
In our solar system, Venus is closest to Earth's size - just slightly smaller at 95% of Earth's radius.
