luto may be tiny, but it did give New Horizons a kick in the pants… This is Pluto in a Minute.
The sphere of influence is the area around a body in space in which anything inside that sphere is controlled more by that body’s gravity than anything else. The gravity we feel on the Earth we express as 1g. Pluto, being much smaller, has a much weaker gravitational pull; it’s only about 0.06gs. So it would make sense that the Earth sphere of influence is much bigger than Pluto’s, right? Not so!
