Biography

Discovery of Sedna, named after the Inuit Goddess who rules the seas and from whom all sea creatures come. Sedna is 8 billion miles away from the Sun, a distance that is 90 times greater than that from the sun to the earth and about three times further than Pluto. Sedna may have a moon in its orbit. Its orbit is an extreme ellipse and it takes 10,500 years to circle the sun. The discoverers at CalTech do not give Sedna nor Pluto planetary status though they acknowledge that astronomers are unable to agree on a precise definition of "planet." Sedna was discovered by Dr. Michael Brown at the California Institute of Technology, Chad Trujillo of the Gemini Observatory, and David Rabinowitz of Yale University. The announcement of its discovery was made on March 15, 2004.

Source Notes

from scientific paper by Michael Brown about its discovery. In addition, Tony Louis writes, "I wrote to Chad Trujillo, one of the discoverers of Sedna at Cal Tech. Here is his response about the time of the discovery: 'The location was Palomar Mountain in Southern California. The time was 2003 Nov 14, 06:32:57 Universal Time.'" PT notes that this is equivalent to November 13, 2003 at 10:32 PM PST. Susan Sarkes writes on 4/27/2004 that she had the following by e-mail from Michael Brown: "Susan --

There are 2 answers, since the pictures are taken robotically and looked at a few days later. The pictures were taken on 14Nov 2003 6:32, 8:03, 9:38 GMT. But I didn't see them and thus "discover" Sedna until 10:50am PST 19 Nov 2003.--Mike"
