List of exoplanets discovered in 2018

This is a dynamic list and may never be able to satisfy particular standards for completeness. You can help by expanding it with reliably sourced entries.

This List of exoplanets discovered in 2018 is a list of confirmed exoplanets that were first observed during 2018.[1]

For exoplanets detected only by radial velocity, the listed value for mass is a lower limit. See Minimum mass for more information.
