Last year from three billion miles away, Pluto sent a “love note” back to Earth, via NASA's New Horizons spacecraft. How far would you At about 4 p.m. EDT on July 13 - about 16 hours before closest approach - New Horizons captured this stunning image of one of Pluto's most dominant features. The “heart,” estimated to be 1,000 miles (1,600 kilometers) across at its widest point rests just above the equator. (The angle of view displays mostly the northern hemisphere.) The heart’s diameter is about the same distance as from Denver to Chicago, in America’s heartland. Tag your hearts desire.
