There are many moons in our Solar System and two planets has most of them. One of them is Saturn, the sixth planet from the Sun and the second-largest in the Solar System, after Jupiter. It is a gas giant with an average radius of about nine times that of Earth.
It is known to have 150 moon-like objects revolving it with 62 confirmed moons. One of them is Enceladus, and in this article we will discuss just about this.
Enceladus is the sixth-largest moon of Saturn. It is about 500 kilometers ( 310 miles ) in diameter, about a tenth of that of Saturn’s largest moon, Titan and was discovered in 1879 by William Herschel and named after the Greek mythological giant Enceladus. Enceladus is mostly covered by fresh, clean ice, making it one of the most reflective bodies of the Solar System reflecting 90% of the Sun’s light.
- Inside out Eruptions
Evidence of liquid water on Enceladus began to accumulate in 2005, when scientists observed plumes containing water vapor spewing from its polar surface, with jets moving 250 kg of water vapor every second up to 2,189 km/h (1,360 mph) into space.
- Puting a Ring on Saturn
Fast-moving ice particles escaping from Enceladus’ jets feed and replenish on of Saturn’s rings, called the E ring, a faint halo that lies beyond the brighter main rings.
- Slipping and Sliding
The icy, cracked terraing stretching across Enceladus’ active south pole is in constant motion, stretching in some places and buckling in others as the cracks pinch and pull from gravitational forces.
- Too Hot to Handle
An usual amount of heat emanates from Enceladus’ south polar region in the same areas where jets spray from massive cracks. The moon’s ability to generate so much internal heat remains a mystery, but it bodes well for habitability.
- Cool Chemestry
Organic compounds, the building blocks of life on Earth along with volatile gases, water, vapor, carbon dioxide, carbon monoxide, salts and silica have been detected in Enceladus’ plume.
