The Trans Neptunian Objects are remnants from the early Solar System formation. They are small icy bodies orbiting the Sun beyond Neptune's orbit. From 1992 onwards, hundreds of new objects, some of them a thousand kilometres in diameter, have been detected. The visible frontier of the solar system has been pushed back, and a new region unveiled: the Kuiper Belt.
Although the reclassification of Pluto is the most visible consequence of these discoveries, it is also one of the least fundamental. The study of these trans-Neptunian objects, at the edge of the solar system, has now become one of the most active branches of planetology. What we are finding beyond the orbit of Neptune is providing us little by little with the key to subjects as diverse and fundamental as the troubled history of the solar system, its ‘architecture’, the origin of comets, and even the formation of lunar craters.
Biography of Dr. Doressoundiram
Dr. Alain Doressoundiram, an astronomer at the Paris Observatory, is a specialist in Solar System. His research interests include planetary surfaces, the small bodies of the solar system. He is also a mass data processing and Statistical Analysis expert.
He is heavily involved in space missions to explore the Solar System. He is co - responsible for an instrument on BepiColombo Mission (mission to Mercury in 2018) and MIOSOTYS, an instrument installed on the floor of the 2.2m Calar Alto Observatory (Spain), Co - I on Phebus (BepiColombo) EXOMARS. Dr.Doressoundriam published over 90 scientific articles in refereed journals, as well as a hundred communications in symposia and author of several popular books.
