5/5/2023 0 Comments Moon atlas saturn![]() "If this is the same object then it has an orbit that crosses the F-ring, which makes it a strange object."īecause of the puzzling dynamical implications of having a body which crosses the ring, the inner object sighted by Spitale is presently considered a separate object with the temporary designation S/2004 S 4. "When I went to look for additional images of this object to refine its orbit, I found that about five hours after first being sighted, it seemed to be orbiting interior to the F-ring," said Spitale. This is because a search through other images that might capture the new object by Dr Joseph Spitale, a planetary scientist at the Space Science Institute in Boulder, Colorado, revealed something strange. Scientists are not sure if the new object is alone. Plasma spectrometer measures charged particles and solar winds Huygens probe will land on Saturn's largest moon, Titanĩ.

It is at a distance of approximately 141,000km (86,000 miles) from the centre of Saturn and within 300km (190 miles) of the orbit of the moon Pandora. If it is a moon, its diameter is estimated to be 4-5km (two to three miles) and it is located 1,000km (620 miles) from the F-ring, Saturn's outermost ring. Scientists cannot yet definitively say if it is a moon or a temporary "clump". It was an incredible privilege to be the first person to spot it." Murray's group at Queen Mary was the first to calculate an orbit for the object. "I noticed this barely detectable object skirting the outer part of the F-ring. It was first seen by Professor Carl Murray, Cassini Imaging Team member at Queen Mary College, University of London, in images taken on 21 June 2004, just days before Cassini arrived at Saturn. The Cassini-Huygens mission is continuing to provide new discoveries at the Saturn system.Ī small object was discovered moving near the outside edge of the F-ring, interior to the orbit of Saturn's moon Pandora. The Cassini-Huygens mission is a joint venture of the US, European and Italian space agencies. University of London scientists working on the four-year mission say that confirmation of another moon would raise Saturn's tally to 34 satellites. The discoveries are in the planet's contorted F-ring region, and look to be associated with Saturn's moon Atlas. Scientists using the Cassini probe have found a new ring and one, possibly two, new objects orbiting Saturn. The new ring is marked in red ( Image: Nasa/JPL/SSI)
