James Webb Space Telescope Distance from Earth

The distance of James Webb Space Telescope from Earth is currently 1,626,749 kilometers, equivalent to 0.010874 Astronomical Units. Light takes 5.4263 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 December 2021 and January 2025, 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.

James Webb Space Telescope rise and set times

Today's James Webb Space Telescope rise, transit and set times from Greenwich, United Kingdom [change] are the following (all times relative to the local timezone Europe/London):

The rise and set times are defined as the time at which the upper limb of James Webb Space Telescope touches the horizon, considering the effect of the atmospheric refraction. As the atmospheric conditions cannot be modeled precisely the times reported here should be considered correct with an approximation of few minutes.

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!
