It is either S/2003 J 9 or S/2003 J 12, both are roughly 1 kilometer in diameter.
Jupiter's smallest moon is called Leda.
Jupiter has 67 natural satellites (or 'moons'). Most of them are less than 10Km in diameter.
The smallest of the Galilean moons is Amalthea, which is one of Jupiter's moons. It is irregularly shaped and has a reddish color due to its surface composition.
It is the smallest of the four inner moons of Jupiter.
The smallest planet is Mercury with a diameter of about 4,880 kilometers, while the largest is Jupiter with a diameter of about 139,820 kilometers. Therefore, the diameter difference between the smallest and largest planet is approximately 135,940 kilometers.
The angular diameter of Jupiter as seen from Callisto is approximately 65 arcminutes. This means that Jupiter appears to be about 1 degree wide in the sky from Callisto, which is one of Jupiter's moons.
Mercury is the smallest planet in terms of diameter among the options provided.
The smallest moons are S/2003 J9 and S/2003 J12, orbiting Jupiter. The biggest moon is Ganymede, also orbiting Jupiter.
Ganymede,Callisto,Io. I put them in biggest to smallest.
Jupiter is the largest planet and Mercury is the smallest planet in our solar system. Extra-solar radii extremes would be HAT-P-32b as the largest and Kepler-42d as the smallest.
Whoever made the question you mean DIAMETER. It is 3,270 miles in diameter
Jupiter, the biggest planet in our astonishing solar system. Jupiter has 60+ known moons. But there are four main moons, Io, Europa, Callisto and Ganymede. Io is 3,630 km in diameter and is 421,600 km away from Jupiter. It is very active, and has constant volcanic eruption. Europa is 3,138 km in diameter and is 670,900 km away from Jupiter. Astronomers think that underneath its crust, it may harbor an ocean. Ganymede is 5,262 km in diameter - the largest moon in our Solar System - and is 1,070,000 km away from Jupiter. Also, this moon could potentially harbor an ocean beneath its crust. Callisto is 4,800 km in diameter and is 1,883,800 km away from Jupiter.
