| | David J. Tholen - Wikipedia, the free encyclopedia |
 | | Tholen has discovered a number of asteroids, including the lost 1998 DK, which may be an Apohele asteroid, and 2004 XZ130, which certainly is; in fact, it has the smallest semimajor axis and aphelion distance among the known asteroids. |
 | | In 1995, Tholen obtained images of the newly-discovered comet Hale-Bopp at a time when the comet was moving very slowly with respect to the background stars, thus permitting the red- green- and blue-filtered images to be combined into a color composite without the background stars appearing as separately colored dots. |
 | | Tholen's Usenet style is unique, characterized by relentlessness and the repetitive use of certain phrases, such as "classic unsubstantiated and erroneous claim"[2], "how ironic"[3], "note: no response"[4], and "non sequitur"[5]. |
