As of 2019, only five space probes are leaving the solar system: Pioneer 10, Pioneer 11, Voyager 1, Voyager 2 and New Horizons. The Voyagers already left the solar system and entered the interstellar space (Voyager 1 on August 25, 2012, and Voyager 2 on November 5, 2018. The others also will leave the heliosphere Notes 1 and reach the interstellar space in a few years.
All of these spacecraft are launched by NASA.

It took 27 years, but finally, NASA’s New Horizons spacecraft beat Voyager 1’s record for being farthest from Earth while capturing images. Taken on December 5, 2017, New Horizons image of the open star cluster NGC 3532 (also commonly known as the Football Cluster or the Wishing Well Cluster) became the farthest image ever made by any spacecraft, breaking a 27-year record set by Voyager 1. But for a very short time! About 2 hours later, New Horizons broke its own record with images of two Kuiper Belt objects.
For a short time, the image below, New Horizons Long Range Reconnaissance Imager (LORRI) frame of the galactic open star cluster NGC 3532 (aka the Football Cluster or the Wishing Well Cluster), taken on December 5, 2017 (released on February 8, 2015), was the farthest image ever made by a spacecraft, breaking a 27-year record set by Voyager 1. New Horizons was 3.79 billion miles (6.12 billion kilometers or 40.9 astronomical units-AUNotes 1) from Earth when LORRI took the routine calibration image.

Twelve years ago, on January 19, 2006, aboard an Atlas V rocket, NASA’s New Horizons probe started its fantastic voyage of exploration with a spectacular launch from the Florida coast toward Pluto and the mysterious realm of the Kuiper Belt beyond.
Video: two views of launch of NASA’s New Horizons spacecraft aboard an Atlas V rocket on January 19, 2006, from Cape Canaveral Air Force Station, Fla. New Horizons was the fastest spacecraft ever launched, leaving Earth at approximately 16.26 kilometers per second (58,536 km/h; 36,373 mph).
