- 2026, transit timing variations (Multiple Observatories)
Masses found by the wobble method are minimums, because the orbit's tilt is unknown. Temperatures are equilibrium estimates for a bare planet, before any atmosphere.
How we know
The shadow
The planet passes in front of its star and dims it by a fraction of a percent, every orbit. The dip gives the planet's size and year.
Early and late
A known planet arrives early or late for its transits, betraying the pull of another, unseen planet.
