Why do some planets have rings?

The rings of Saturn are magnificent. They are bright, wide, and colourful. Uranus has nine dark rings around it. Neptune's rings are also dark. The rings of Jupiter is thin and dark.

Scientists have not come to an agreement on the origin of these rings. The rings may have formed from the dust knocked off the planet's moons when they were bombarded by meteoroids. Some of them might have come from moons torn apart by the gravity of the planet, or they could have formed as the planet's formed. 

The rings of Jupiter, Uranus, and Neptune are made of dust, and very tiny pieces of rock and ice. The rings of Saturn are made of large particles of ice.  

Why is Jupiter hot and cold at the same time?

Jupiter is the fifth planet from the Sun, and the largest in the Solar System.

Jupiter is a gas giant, along with Saturn. It is colder than Antarctica. The surface temperature of Jupiter is 1500 degree Celsius. The surface of Jupiter is a thick mass of ice that never melts, as it receives hardly any heat from the Sun. Jupiter is five time farther away from the Sun when compared to the Earth.

Jupiter was called a gas giant. Also, it was not possible to find out whether a solid layer existed below the ice.

The surface of Jupiter is made of ice, but hot molten material exists inside. The hot molten material was discovered in recent years by astronomers, with radio telescopes. What lies in between the two layers remains a mystery. Some scientists believe that an insulating material separates the two. Others believe that water separates the two layers.

A VISIBLE PLANET

Jupiter is the fourth brightest object in the solar system. Only the Sun, Moon, and Venus are brighter.

 It is one of five planets visible to the naked eye from Earth. It is popularly known as a "Gas giant".
