<p>I am hoping to find axial tilts for asteroids and also their spring and fall equinox. Some of the asteroids I'm interested in are:
4 Vesta, 1 Ceres, 24 Themis, 65 Cybele, 153 Hilda, 624 Hektor</p>

Is there online data on asteroid axial tilts?

From this article, <http://hubblesite.org/pubinfo/pdf/2010/33/pdf.pdf>, here's the rotation axis for 4 Vesta: RA=307.5°±3.1°, Dec=43.1°±1.2°. Update, per TildalWave's comment: [RA=305.8°±3.1°, Dec=41.4°±1.5°](http://www.sciencedirect.com/science/article/pii/S0019103510003726)
