It is estimated to be 440 light years distant based on parallax measurements.
[4] A 2005 paper suggests that Platais 8 might have formed near the area where the Scorpius-Centaurus association is located.
In fact, there are only 32 members physically associated with the cluster.
[1] The cluster has a combined mass of 546 M☉ and a radius of 37.2 light years.
[3] These are the members of the cluster as identified by Canat-Gaudin et al. (2018) The cluster also has one potential stream star located in Volans[1] and was considered to be a background object prior to 2020.
