After launch, a “fast flyby” mission like New Horizons following this JGA trajectory would continue on to pass by Jupiter on May 11, 2030, with a closest approach altitude of 2.08 Jupiter-radii, or just inside the orbital distance of Io. This would offer a better vantage point to observ...
Pluto's mean distance from the sun is 3.67 billion mi (5.91 billion km), and its period of revolution is about 248 years. Since Pluto has an orbit that is more elliptical and tilted than those of the planets (eccentricity .250, inclination 17°), at its closest point to the sun it ...
