‘Planet confusion’ could slow Earth-like exoplanet exploration

Researchers warn that future exoplanet direct-imaging missions need to make multiple observations to differentiate between planets. In 36% of solar systems, an Earth-like planet can be misidentified with a Mercury-like planet, and in 72% of cases, it could be mistaken for a Venus-like planet.
