an impact per year on Jupiter, from considerations relating to the craterization of the surfaces of the satellites; [63] 30–100 collisions per year, basing the data on asteroid and cometary populations near the planet's orbit. [63] For comparison, a frequency of impact with an object of this size every 6–15 years has been estimated for the ...

An asteroid that’s somewhere between 30 and 100 feet long is hurtling through space in the direction of Earth at 30,000 miles per hour. Asteroid 2012 TC4 is going to fly by Earth on October 12 ...
A list of known near-Earth asteroid close approaches less than 1 lunar distance (384,400 km or 0.00257 AU) from Earth in 2012. [note 1] Rows highlighted red indicate objects which were not discovered until after closest approach
The mission will help researchers peer back in time to learn how the solar system formed 4.5 billion years ago and unlock how planets ended up in their current spots. For more CNN news and ...
