The light curve of asteroid 1998 SF36, observed in 2001 The horizontal axis is called the rotation phase and covers one complete rotation. The vertical axis is the relative value of the asteroid's brightness. "Relative value" means the exact value on the vertical axis does not mean anything. Instead, you should look at the amount of change in the brightness. M. Kaasalainen et al. A&A 405, L29-L32, 2003
