Nope...In the 1980's some astronomers predicted that Triton would be pulled ever closer to Neptune until, in 100 million years, it would be torn apart to form a ring around Neptune. But Voyager measurements of the gravitational field of Neptune show that its tidal influence on Triton is no longer great enough to cause the satellite's orbit to shrink quite this fast. Computer modeling of the orbit by astronomer C. F. Chyba ( 1989, Astronomy and Astrophysics, vol. 219, p. L23) now show it shrinking from its present 14.3x Neptune's radius to only 12.5 times Neptune's radius, and taking over 5 BILLION years to do so. Triton, given the evolution of the Sun into a red giant, will outlast the Earth.
