Pioneer 10

Altitude: -6.0°   Azimuth: 327.0°   Direction: North-North-West

Pioneer 10 was the first spacecraft to traverse the asteroid belt and make a flyby of Jupiter, providing valuable data on the gas giant and its moons. Launched on March 2, 1972, Pioneer 10 was the first spacecraft to achieve escape velocity from the Solar System and enter interstellar space. Its mission ended on March 31, 1997, after over 25 years of operation and communication with Earth. Pioneer 10 carried a plaque designed to serve as a message to any extraterrestrial life that might encounter the spacecraft in the future. The plaque depicted a man and a woman, along with various symbols and information about our location in the galaxy. Pioneer 10 has now traveled over 12 billion miles away from Earth.

Pioneer 10 is currently in the constellation of Taurus, at a distance of 20,307,001,502 kilometers from Earth.

Visualization of Pioneer 10 Orbit

This 3d orbit diagram is a feature of our 3D Solar System Simulator and shows the orbit of Pioneer 10 with respect of the Sun and the orbits of the major planets. The position of Pioneer 10 and the planets along their orbits in this diagram accurately represents the current configuration of the objects in the Solar System. This is an experimental feature and it requires a WebGL enabled browser. Please provide us feedback!
