Does Jupiter have a greenhouse effect?

The greenhouse effect describes a warming phenomenon. The greenhouse effect can also be found on Earth and in the upper atmospheres of the giant planets: Jupiter, Saturn, Uranus, and Neptune. The greenhouse effect refers to the way in which gases in our planet’s atmosphere can keep heat from escaping into space.

What does radiative equilibrium refer to?

Radiative equilibrium assumes that incoming radiative energy from the Sun is equal to the outgoing radiation emitted by the planet: incoming energy = outgoing energy. In other words, the planet is in energy balance. If radiative equilibrium is not achieved, then the temperature of the planet must rise or fall.

Why does Jupiter give off more heat than it receives from the Sun?

The outer edges of Jupiter’s atmosphere are much cooler than the core region. The molten inner regions of the planet serve to heat the rest of the planet through convection, so Jupiter gives off more heat than it receives from the Sun.

Does Jupiter give off radiation?

Jupiter’s Magnetic Field and Radiation Belts Jupiter is surrounded by an enormous magnetic field called the magnetosphere, which has a million times the volume of Earth’s magnetosphere. Charged particles are trapped in the magnetosphere and form intense radiation belts.

How do the differences in the interiors of Saturn and Jupiter affect the planets magnetic fields?

Jupiter has a larger metallic hydrogen core than Saturn, and the larger this region is the stronger a magnetic field can be. Because of the two planets’ similar rotation periods, the difference in the magnetic fields must come from the differential core sizes.

What planet has no greenhouse effect?

As a complete contrast to Venus, there is Mars. The Red Planet displays hardly any greenhouse effect. Mars does have some atmospheric carbon dioxide, but almost no atmosphere! The existing atmosphere is so thin that it cannot retain energy from the Sun.

Which planet has the least greenhouse effect?

Mars
Mars’ atmosphere is composed mainly of carbon dioxide, but there is so little carbon dioxide overall that the greenhouse effect is essentially negligible. This, coupled with the distance from the sun means that the temperature of Mars is significantly lower than the Earth’s temperature.

Why is Earth in radiative equilibrium?

The energy that Earth receives from sunlight is balanced by an equal amount of energy radiating into space. When the flow of incoming solar energy is balanced by an equal flow of heat to space, Earth is in radiative equilibrium, and global temperature is relatively stable.

What is Earth’s global radiative equilibrium without the greenhouse effect?

The temperature at which this occurs is about 0 F. That is called the temperature of radiative equilibrium. You might remember this is the figure for global annual average surface temperature on the earth without the greenhouse effect.

Why is Jupiter’s core hot?

Jupiter’s core temperature is thought to be about 20,000 degrees Celsius (36,000 degrees Fahrenheit). Jupiter appears to still be contracting as part of its formation process. As it contracts, the gravitational energy of material falling towards the center releases heat, contributing to the core’s high temperature.

Why is Jupiter’s radiation so powerful?

It is Jupiter’s combination of a strong magnetic field, Io’s prodigious source, and the magnetic coupling of charged particles to the planet’s rapid (10-hour) spin that drives the intense radiation. Earth’s radiation belts (named after James Van Allen, who discovered them with the U.S.’s first satellite in 1958) are much weaker.

What is the difference between Jupiter and Earth’s radiation belts?

Earth’s radiation belts (named after James Van Allen, who discovered them with the U.S.’s first satellite in 1958) are much weaker. Saturn, Uranus, and Neptune also have radiation belts — but, again, these are much weaker than Jupiter’s. Jupiter’s magnetosphere is the largest structure in the solar system.

Where do Jupiter’s protons come from?

The source of the protons is some combination of particles escaping from Jupiter’s ionized atmosphere (the ionosphere) and particles leaking in from the solar wind. The dominant particle source, however, is the volcanic moon Io, which dumps a ton per second of sulfur dioxide gas into space where the molecules are broken up and ionized.

What is Jupiter’s magnetosphere?

The huge region around the planet where Jupiter’s magnetic field controls the environment is called its magnetosphere. Any charged particles in the space around Jupiter will experience the planet’s strong magnetic field and get accelerated to high energies.
