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.
Most asteroids lie in a vast ring between the orbits of Mars and Jupiter. This main asteroid belt holds more than 200 asteroids larger than 60 miles (100 kilometers) in diameter.Scientists estimate the asteroid belt also contains more than 750,000 asteroids larger than three-fifths of a mile (1 km) in diameter and millions of smaller ones.early all asteroids are irregularly shaped, although a few are nearly spherical, such as Ceres. They are often pitted or cratered â for instance, Vesta has a giant crater some 285 miles (460 km) in diameter. The surfaces of most asteroids are thought to be covered in dust.
