Professional Life

David James Tholen is an American astronomer at the Institute for Astronomy of the University of Hawaii, who specializes in planetary and solar system astronomy. Roy A Tucker (born 1951 Jackson Mississippi) is an American Astronomer. Historically Astronomy was more concerned with the classification and description of phenomena in the sky while Astrophysics attempted to explain these phenomena The Institute for Astronomy (IfA is a research unit within the University of Hawaii system led by Dr The University of Hawaii, formally the University of Hawaii System and popularly known as UH, is a public co-educational college and university system that confers Planetary science, also known as planetology and closely related to planetary astronomy, is the Science of Planets or Planetary systems The Solar System consists of the Sun and those celestial objects bound to it by Gravity. Tholen has discovered a number of asteroids, including the lost 1998 DK36, 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. Asteroids, sometimes called Minor planets or planetoids', are bodies—primarily of the inner Solar System —that are smaller than planets but (also written 1998 DK36) is possibly the first Apohele asteroid (asteroid that is always closer to the Sun than Earth detected He won the H. C. Urey Prize in 1990. The Harold C Urey Prize is awarded annually by the Division for Planetary Sciences of the American Astronomical Society. Year 1990 ( MCMXC) was a Common year starting on Monday (link displays the 1990 Gregorian calendar) [2]

He co-discovered the asteroid 99942 Apophis (previously known as 2004 MN4). TemplateInfobox Planet. --> 99942 Apophis (əˈpɒfɪs previously known by its provisional designation TemplateInfobox Planet. --> 99942 Apophis (əˈpɒfɪs previously known by its provisional designation This asteroid will closely approach Earth on 13 April 2029 and very briefly appear as bright as a third magnitude star. Events 1111 - Henry V is crowned Holy Roman Emperor. 1204 - The Fourth Crusade sacks Constantinople 2029 ( MMXXIX) will be a Common year starting on Monday of the Gregorian calendar. The apparent magnitude ( m) of a celestial body is a measure of its Brightness as seen by an observer on Earth, normalized to the value

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. Comet Hale-Bopp ( formally designated C/1995 O1) was probably the most widely observed Comet of the twentieth century and one of the brightest This color composite image was made publicly accessible via the Institute of Astronomy's web site.

Later, Olivier Hainaut discovered that this image was nearly identical to the one being discussed by late-night radio host Art Bell and one of his guests, Courtney Brown, who claimed that the image proved the existence of an unnatural object following the comet, something supposedly seen by those who had learned how to engage in the technique of "remote viewing". Arthur W "Art" Bell III (born June 17, 1945) is an American broadcaster and Author, known primarily as the founder and Courtney Brown PhD is a Social scientist at Emory University and is known for promoting the use of nonlinear mathematics in social scientific Remote Viewing (RV refers to the attempt to gather information about a distant or unseen target using paranormal means or Extra-sensory perception. The image provided to Bell by Brown, and eventually made public on Bell's web site, did indeed show an object next to the comet that did not appear in archival images of the sky. In reality, the original image obtained by Tholen had been digitally altered, presumably by taking the image of a star near the edge of the frame, adding it to image next to the comet, and then trimming away the outer edges of the frame.

Tholen and Hainaut exposed the fraud by producing the original image, which showed no such additional object. Nevertheless, some people maintained that Brown's version was the original image and that Tholen had removed the additional object from the one on the Institute's web site. Indeed, the Heaven's Gate cult was so convinced that the additional object was a spaceship coming to take them away from Earth that they committed mass suicide. Heaven's Gate was an American UFO religion based in San Diego California and led by Marshall Applewhite (1932-1997 and Bonnie Nettles (1927-1985 Mass suicide occurs when a number of people kill themselves together and/or for the same reason

Personal Interests

David Tholen and Roy Tucker, co-discovers of 2004 MN4, are both fans of the TV series Stargate SG-1, which influenced the naming of the asteroid. The show's most persistent villain is Apophis, an alien also named for the Egyptian god. "We considered a number of names, but 'Apophis' kept floating to the top," says Tucker. "Apophis was a very fitting name for 2004 MN4 not only because of its threatening nature, but also because of its evolution from an Aten asteroid to an Apollo asteroid during the 2029 encounter. " . [3]

Tholen is a fan of the University of Kansas Jayhawks college basketball team and the Kansas City Royals Major League Baseball team.

He also plays bass clarinet for the Honolulu Community Concert Band.

He is also an avid user and advocate of the OS/2 operating system.
