Works by Eudoxus are all lost, apart from some fragments preserved in Hipparchus' commentary on Aratus's poem on astronomy.
The titles of some of Eudoxus' works are:
- Disappearances of the Sun, possibly on eclipses
- Oktaeteris (Ὀκταετηρίς), on an eight-year lunisolar cycle of the calendar
- Phaenomena (Φαινόμενα) and Entropon (Ἔντροπον), on spherical astronomy, probably based on observations made by Eudoxus in Egypt and Cnidus
- On Speeds, on planetary motions
