Google product developer Clay Bavor created a gif putting the Boeing 747 and SR-71 aircraft speeds into perspective compared to NASA’s New Horizons spacecraft.
NASA’s New Horizons probe started its fantastic voyage of exploration on January 19, 2006, aboard an Atlas V rocket. directly into an Earth-and-solar-escape trajectory with a speed of about 16.26 km/s (10.10 mi/s; 58,500 km/h; 36,400 mph). It was the fastest man-made object ever launched from Earth.
It swung past Jupiter for a gravity boost and scientific studies in February 2007 which increased New Horizons’ speed, and conducted a six-month-long reconnaissance flyby study of Pluto and its moons in summer 2015, culminating with Pluto closest approach on July 14, 2015.
However, New Horizons is not the fastest spacecraft to leave the Solar System. As of January 2018, this record is held by Voyager 1, traveling at 16.985 km/s (61,146 km/h; 37,994 mph) relative to the Sun. Voyager 1 attained greater hyperbolic excess velocity than New Horizons thanks to gravity assists by both Jupiter and Saturn.
New Horizons flew 12,500 km (7,800 mi) above the surface of Pluto, making it the first spacecraft to explore the dwarf planet.
After completing Pluto flyby, it made a total of four trajectory changes in October and November 2015 to place itself on a course towards Ultima Thule, a trans-Neptunian object located in the Kuiper belt.
The Ultima Thule flyby occurred on January 1, 2019, when the spacecraft was 43.4 AU from the Sun.
The Kuiper Belt stretches from about 30 (the orbit of Neptune) to about 55 astronomical units (AU) from the Sun. It is similar to the asteroid belt, which is located roughly between the orbits of the planets Mars and Jupiter but is far larger- 20 times as wide and 20 to 200 times as massive. Like the asteroid belt, it consists mainly of small bodies or remnants from when the Solar System formed.
