A FAQ on the Antarctic Ozone hole A collection of FAQs on ozone depletion Home page for NASA's Total Ozone Mapping Spectrometer. The page is furnished with lesson plans, activities, and links to related material. He suggests that the object is several times larger than Jupiter and lies 30,000 times farther from the sun than the earth, that is, around 750 times further out than Pluto in the direction of the constellation of Delphinus. The work is to be reported in a paper to be published next week in the Monthly Notices of the Royal Astronomical Society. Professor John Matese, of the University of Louisiana at Lafayette, has carried out a similar study and reached broadly similar conclusions.

. Friday, 8 October 1999 A scientist at the Open University in the UK argues that the gravity from a large, undiscovered object in orbit around the Sun could be the explanation for the unusual paths of near-Earth comets. In the upcoming issue of the Monthly Notices of the Royal Astronomical Society, Dr John Murray sets out a case for an object orbiting the Sun 32,000 times farther away than Earth. (One astronomical unit is approximately the average distance between the Earth and the Sun. ) They reach Earth's vicinity in the inner solar system when their usual, remote orbits are disturbed.

Many issues of Astronomy Now are still available, including older magazines available only online. . Writing in the issue of the Monthly Notices of the Royal Astronomical Society published on 11th October, Dr John Murray sets out a case for an object orbiting the Sun 32,000 times farther away than Earth. It would, however, be extremely faint and slow moving, and so would have escaped detection by present and previous searches for distant planets. (One astronomical unit is approximately the average distance between the Earth and the Sun.

. Currently, Pluto is the planet we think of being on the edge of our planetary system. But the new body would be 30,000 times more distant from the Sun than the Earth - putting it a significant distance on the way to the nearest star. What is more, it seems that the new planet cannot be a true member of our Sun's family of planets. It may be a planet that was born elsewhere, and roamed throughout the galaxy only to be captured on the outskirts of our own Solar System.
