Delta Hydrae is about  from Zeta Hydrae and may be a largely co-moving object. The star has one of the lower-error margin readings among those of the Gaia spacecraft which computes a parallax of 20.7182 ± 0.3925 mas and, if correct, a distance of 157 ± 3 light years.
Delta Hydrae is roughly from Zeta Hydrae and could be a co-moving object. The star has one of the least uncertain measurements by Gaia, which provides a parallax of 20.7182 ± 0.3925 mas and, if correct, places it at a distance of 157 ± 3 light years.
