New Delhi, 31 Berezno (GCCurrentAffairs) Dr. JJ Rava, the then director of research, Nera planetarium Nera Center, Worli, Mumbai and now President of the Indian planetary society, even in 1981 and 1989 predicted the existence of the New Moon of Neptune.

It is predicted on the basis of the solar system, the satellite system Jupiter, Uranus and Neptune under compressive from Roche and resonance systems.

The document containing the existence of this, an unknown companion, was published in the scientific journals Science International Earth, moon and planets 44, 265-274, 1989, entitled "Narrowing the sub-solar nebula", according to the Indian Planetary Society Secretary General Viren F Dave.

The satellite is only 32 km in diameter and orbits the planet at a distance of 1,05,250 km from Neptune and takes 23 hours or a day in the orbit of the planet.

This Neptunain satellite was discovered by a team led by Mark Showalter of the Search for Extraterrestrial Intelligent (SETI) Institute in Mountain View, California, by analyzing photographs taken by NASA's Hubble Space Telescope in 2004 and 2009.
