Before you call the contractor and start picking out float toys, letâs make sure you know what youâre getting into. The average in-ground swimming pool costs $21,919, according to home improvement site Fixr. And thatâs for a pretty basic 32â by 16â model. But thatâs just to build the thing. Then you have to take care of it.
The large majority of known asteroids orbit in the asteroid belt between the orbits of Mars and Jupiter, or are co-orbital with Jupiter (the Jupiter trojans). However, other orbital families exist with significant populations, including the near-Earth objects.
The largest asteroid by far is 1 Ceres. It is 974 km in diameter and contains about 25% of the mass of all the asteroids combined. The next largest are 2 Pallas, 4 Vesta and 10 Hygiea which are between 400 and 525 km in diameter. All other known asteroids are less than 340 km across. There is some debate as to the classification of asteroids, comets and moons. There are many planetary satellites that are probably better thought of as captured asteroids.
