On April 10 2020, the Mercury probe BepiColombo will fly past the Earth.
The Earth will provide a "gravity assist" and is the first of several flybys of the Earth, Venus and Mercury before it arrives in
Mercury orbit in 2025.
If you know where to look and live in the right part of the world, you will have a chance to see it through binoculars or a telescope.
You can use the two general charts below and the following table to get an idea of whether you will be able to see it or not.
Click on a table row to load a finder chart corresponding to that time, or alternatively, you can go straight to a finder chart for a time near closest approach by clicking here.
Note: All times in the tables and charts are given in your local time, adjusted for daylight savings where appropriate.
