James Webb Space Telescope
The James Webb Space Telescope (JWST) is a large, infrared-optimized space telescope launched on 25 December 2021. It is a joint project between NASA, the European Space Agency (ESA), and the Canadian Space Agency (CSA). The primary scientific objectives of the JWST include studying the early universe, galaxy formation and evolution, and the formation of stars and planetary systems. The telescope is also used to study the atmospheres of exoplanets to search for signs of life. The JWST is positioned at the second Lagrange point (L2) of the Earth-Sun system, located about 1.5 million km (930,000 mi) away from Earth, and uses a 6.5-meter primary mirror to collect and focus infrared light from the most distant objects in the universe.
James Webb Space Telescope is currently in the constellation of Ophiucus, at a distance of 1,661,232 kilometers from Earth.

James Webb Space Telescope Distance from Earth
The distance of James Webb Space Telescope from Earth is currently 1,661,232 kilometers, equivalent to 0.011105 Astronomical Units. Light takes 5.5413 seconds to travel from James Webb Space Telescope and arrive to us.
The following chart shows the distance of James Webb Space Telescope from Earth as a function of time. In the chart the distance data is measured in Astronomical Units and sampled with an interval of 1 day.
The value of the reported distance might be somewhat inaccurate around the times of closest approach for objects passing extremely close to Earth. The value of the distance of James Webb Space Telescope from Earth is also available as a real time updated value in the Live Position and Data Tracker.
Closest Approach of James Webb Space Telescope to Earth
Between 26 December 2021 and 12 May 2029, the closest approach of James Webb Space Telescope to Earth happens on Sun Dec 26 2021 at a distance of 0.000894 Astronomical Units, or 133,698 kilometers:
NOTE: values for the closest approach are computed with a sampling interval of 1 day.
Visualization of James Webb Space Telescope Orbit
This 3d orbit diagram is a feature of our 3D Solar System Simulator and shows the orbit of James Webb Space Telescope with respect of the Sun and the orbits of the major planets. The position of James Webb Space Telescope 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!
