# What's the influence of a tilted orbital plane, when observing an exoplanet transit?

I made an illustration to explain what i mean : If we assume we have two similar planet/star systems (similars in size/mass/period..) but tilted differently relative to us. How can we predict that differences in dimming measurements (time & intensity) are caused by the tilting of orbital plane? (and not by the diameter of the exoplanet)

• If I understand the question, the (tiny) apparent angular size of the star from Earth is not relevant, It is the size of the star relative to the size of the planet and its orbit. I think there is a good question here. Apr 3 '17 at 21:06
