This gives Pluto an escape velocity of 4,363.2 km per hour / 2,711.167 miles per hour (as compared to Earth's 40,270 km per hour / 25,020 miles per hour). Pluto is more than twice the diameter and a dozen times the mass of Ceres , the largest object in the asteroid belt .
Photographs of Pluto taken on 14 July 2015 taken 15 minutes after New Horizon 's closest approach, from a distance of 18,000 kilometers and sent to Earth on 13 September 2015 show a near-sunset on Pluto with details of the surface and a haze in the atmosphere.
New Horizons encounters Pluto at a distance of 4.7 billion kilometres, and the communication takes 4 hours 25 minutes to reach Earth. 10 −3: 2.04 × 10 −3 ly: The most distant space probe, Voyager 1, was about 18 light-hours (130 au,19.4 billion km, 12.1 billion mi) away from the Earth as of October 2014.

This is because New Horizons would require approximately 16 months after leaving the vicinity of Pluto to transmit the buffer load back to Earth. [67] At Pluto's distance, radio signals from the space probe back to Earth took four hours and 25 minutes to traverse 4.7 billion km of space. [68]
Every day for the next sixteen months, we’re going to get something new from the Pluto system. Scientists will pore over the data—they’re going to be coming up with new theories for probably 10, 20 years. RM: So many adults get their sense of wonder beaten out of them, but you still seem genuinely enchanted by what’s out there. AB: I am ...
Scientists have long theorized that Charon formed much like Earth’s moon, which was created after a Mars-size object slammed into our planet. The impact sent molten debris from Earth flying into ...
It is 2,990 km (1,860 mi) long and is the largest dark feature on Pluto. [18] It is the largest of the dark regions ( Brass Knuckles ) that span Pluto's equator. [ 16 ] The dark color of the area is speculated to be the result of a "tar" made of complex hydrocarbons called tholins covering the surface, formed from methane and nitrogen in the ...
