About this Dataset

Gaia 626k Stars From DR3 (Data Release 3) V2

2nd version of the dataset https://www.kaggle.com/datasets/realkiller69/gaia-data-set-for-stellar-classificationdr3 dedicated to stellar classification. Upto 50 columns added for each instance of data.

626016 data instances filtered from gaia DR3.

100k instances for each spectral class : B, A, F, G, K, M.
26016 for O type stars.
