Welcome to the Astroneo Star Explorer. Use the filters below to navigate through over 8,800 celestial objects cataloged from the Hipparcos mission. You can filter stars by constellation to find objects in specific regions of the night sky, or by spectral class (O, B, A, F, G, K, M) to find stars of specific temperatures and colors—from hot, massive blue giants to cool, dim red dwarfs. Click on any star to view its complete properties, including its distance from Earth, apparent magnitude, and a fully interactive 3D model.
