Simulation of the New Horizons Pluto-Charon flyby

Simulation of the New Horizons Pluto-Charon flyby

Posted 2015/08/13 | 0 comments

An animation showing the New Horizons Pluto flyby on July 14, 2015. The time covered is 09:35 to 13:35 (closest approach occurred near 11:50). Pluto's atmosphere is included and should be fairly realistic from about 10 seconds into the animation and to the end. Earlier it is largely just guesswork that can be improved in the future once all data has been downlinked from the spacecraft. Light from Pluto's satellite Charon illuminates Pluto's night side but is exaggerated here, in reality it would be only barely visible or not visible at all.

Charon's progression: June 22 to July 1, 2015 (third-to-last Pluto day before New Horizons encounter)

Pluto nearly doubled in apparent size in New Horizons' forward view between June 22 and July 1, 2015. This period covered more than one Pluto day.
