List of exoplanets discovered in 2026

This list of exoplanets discovered in 2026 is a list of confirmed exoplanets that were first reported in 2026. For exoplanets detected only by radial velocity, the listed value for mass is a lower limit. See Minimum mass for more information. For exoplanets detected only by direct imaging or microlensing without a determined orbit, the listed value for semi-major axis is the projected separation.

Lists of exoplanets by year of discovery

Notes

  1. ↑ Mass determination depends on whether the orbit is prograde or retrograde.
  2. ↑ Mass determination depends on whether the star is an Ophiuchus or Upper Scorpius association member.
  3. 1 2 3 4 Estimated using theoretical mass–radius relations.
  4. ↑ Converted from orbital period.
