Correction to: Nature Astronomy https://doi.org/10.1038/s41550-020-1032-4, published online 12 February 2020.

In the version of this Editorial originally published, in the second paragraph the text ‘After a 42-million-km journey it will reach a highly elliptic orbit with perihelion 0.28 au (and aphelion 1.2 au)’ was incorrect; it should have read ‘It will get to within 42 million km (0.28 au) of the Sun in a highly elliptic orbit (with aphelion 1 au)’. This has now been corrected.
