Pioneer 11

Altitude: -3.8°   Azimuth: 99.2°   Direction: East

Pioneer 11 was a space probe launched by NASA in 1973 with the goal of studying the outer Solar System. It was the second spacecraft to flyby Jupiter and the first to visit Saturn. After completing its mission, Pioneer 11 continued to transmit data until 1995, when it became too weak to communicate with Earth. It is currently traveling through space in the direction of the constellation Aquila.

Pioneer 11 is currently in the constellation of Scutum, at a distance of 16,752,659,231 kilometers from Earth.

Visualization of Pioneer 11 Orbit

This 3d orbit diagram is a feature of our 3D Solar System Simulator and shows the orbit of Pioneer 11 with respect of the Sun and the orbits of the major planets. The position of Pioneer 11 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!
