The Planets’ Size Comparison

A planet is a heavenly figure circling a star or stellar remainder that is monstrous enough to be adjusted by its particular gravity, is not colossal enough to create thermonuclear combination, and has cleared its neighboring area of planetesimals. The term planet is antiquated, with ties to history, science, mythology, and religion. The planets were basically viewed by a considerable number of early societies as heavenly, or as emissaries of divinities.

The approach could even be tried with the Dawn spacecraft, scheduled to finish its tasks in the asteroid belt by 2015. However, such a strategy would be very slow, requiring years or even decades to alter the path of the asteroid.
