BepiColombo
BepiColombo is a joint mission between the European Space Agency (ESA) and the Japan Aerospace Exploration Agency (JAXA) to study Mercury, the smallest and least explored planet in our solar system. The mission consists of two spacecraft: the Mercury Planetary Orbiter (MPO) built by the ESA, and the Mercury Magnetospheric Orbiter (MMO) built by JAXA. The spacecraft were launched on October 20, 2018, aboard an Ariane 5 rocket from French Guiana. The primary scientific objectives of the mission are to study Mercury's magnetic field, its composition, the geology of its surface, and its interaction with the solar wind. The mission will also investigate the planet's exosphere and study its geological history. BepiColombo is expected to arrive at Mercury in December 2025, after several gravity assist flybys of Earth, Venus, and Mercury itself.
BepiColombo is currently in the constellation of Cetus, at a distance of 170,857,251 kilometers from Earth.

BepiColombo Distance from Earth
The distance of BepiColombo from Earth is currently 170,857,251 kilometers, equivalent to 1.142110 Astronomical Units. Light takes 9 minutes and 29.9184 seconds to travel from BepiColombo and arrive to us.
The following chart shows the distance of BepiColombo 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 BepiColombo from Earth is also available as a real time updated value in the Live Position and Data Tracker.
Closest Approach of BepiColombo to Earth
Between 21 October 2018 and 26 March 2026, the closest approach of BepiColombo to Earth happens on Fri Apr 10 2020 at a distance of 0.000582 Astronomical Units, or 87,050 kilometers:
NOTE: values for the closest approach are computed with a sampling interval of 1 day.
Visualization of BepiColombo Orbit
This 3d orbit diagram is a feature of our 3D Solar System Simulator and shows the orbit of BepiColombo with respect of the Sun and the orbits of the major planets. The position of BepiColombo 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!
