The Semi-major axis ^? is a descriptor of the distance between the exoplanet and its host star. The unit used here is the astronomical unit ^? AU ^? , defined as the Earth-Sun distance, i.e. 150,000,000 km.
As a reminder, the semi-major axes ^? of the planets in the Solar System are: 0.38 AU ^? for Mercury, 0.72 AU ^? for Venus, 1 AU ^? for Earth, 1.52 AU ^? for Mars, 9.57 AU ^? for Jupiter, 19.30 AU ^? for Saturn, 30.21 AU ^? for Uranus, and 39.91 AU ^? for Neptune.
