  The exoGravity project is based around a 14 night long large program to cover multiple known directly imaged exoplanets in multiple epochs using the VLTI/GRAVITY instrument (K-band spectrograph). This allows the team to study the astrometry and spectroscopy (at up to $R=4000$) of these planets and their atmospheres.
