Absolute magnitude from an absolute magnitude in a specific filter band to absolute bolometric magnitude, a bolometric correction is applied. For Solar System bodies that shine in reflected light, a different definition of absolute magnitude (H) is used, based on a standard reference distance of one astronomical unit. In stellar and galactic astronomy, the standard distance is 10 parsecs (about 32.616 light-years, 308.57 petameters or 308.57 trillion kilometres). A star at 10 parsecs has a parallax of 0.1″ (100 milliarcseconds). Galaxies (and other extended objects) are much larger than 10 parsecs, their light is radiated over an extended patch of sky, and
Penske PC-26 over from 1996 and remained a Penske-exclusive system. The PC26 proved to be a formidable short oval car, Paul Tracy recorded three victories in Rio, Nazareth and Gateway. The victory at Gateway marked the 99th for the team and the final victory for a Penske Cars-produced chassis. Penske Racing would have to wait three years to gain its 100th victory. The latter part of the season saw a variety of problems including an eye problem for Tracy as well as a lack of raw pace.
