The tilt of the rotation axis of the gas giant Saturn may in reality be caused by itsmoons, scientists from CNRS, Sorbonne University and therefore the University of pisa havereported.

·        Recent observations have shown that Titan and therefore the different moons are graduallymoving away from Saturn a lot of quicker than astronomers had previously estimated.

·        The researchers concluded that this method affects the inclination of Saturn’srotation axis: as its satellites move more away, the planet tilts a lot of andmore.

·         The current tilt of Saturn’s rotation axis is caused by the migration of its satellites,and especially by that of its largest moon, Titan.

Saturn

·        Saturn is similar to Jupiter, although about one-third the mass. It spins so fast thatits diameter at the equator is 10 percent larger than its diameter from pole to pole.

·         Saturn has a solid core likely made of rock and ice, which is thought to be manytimes the mass of Earth.

·         Covering this core is a layer of liquid metallic hydrogen, and on top of that are layersof liquid hydrogen and helium.

·         These layers conduct strong electric currents that, in turn, generate Saturn’spowerful magnetic field.

Saturn’s Moons

·         Saturn has 62 confirmed moons, and its largest moon is Titan, which is larger thanEarth’s own moon and has a thick, opaque atmosphere.

·         Titan is the second-largest moon in the Solar System (larger than Mercury) and it isthe only satellite in the Solar System with a substantial atmosphere(nitrogen-rich).

Saturn’s Ring System

·         The most spectacular part of Saturn is its magnificent system of planetary rings,which stretch some 300,000 kilometers across. The ring system is divided into threemain parts: the bright A and B rings and the dimmer C ring.

·         Saturn’s rings are probably made up of billions of particles of ice and ice-coveredrocks.

 

Additional Information

CASSINI MISSION

·        The Cassini–Huygens mission, ordinarily known as Cassini, was a collaborationbetween NASA, the european space Agency, and also the Italian space Agency to send aprobe to check the earth Saturn and its system, as well as its rings and naturalsatellites.

 DRAGONFLY MISSION

·         Dragonfly aims to look for signs of microbial alien life on Saturn’s moon Titan,while navigating its earth-like gravity and aerodynamics within the process.

·         The mission can succeed NASA’s Cassini probe, that concluded its 13-year missionorbiting Saturn in September 2017 by diving into Saturn’s atmosphere.

·         Dragonfly mission may be a a part of NASA’s New Frontiers program, that includesa series of space exploration missions, that are being conducted with the purposeof researching many of the solar system bodies, including the dwarf planet Pluto.

·         The New Frontiers programme additionally includes Pluto probe New Horizons,Jupiter probe Juno and OSIRIS-Rex asteroid mission.
