How did temperature influence the formation of planets?

How did temperature influence the formation of planets?

At temperatures hotter than the freezing point of water, light gases, like hydrogen and helium, likely had too much energy to condense together to form the large, gas-giant, Jovian planets.

What explains the formation of the planets?

The Sun and the planets formed together, 4.6 billion years ago, from a cloud of gas and dust called the solar nebula. A shock wave from a nearby supernova explosion probably initiated the collapse of the solar nebula. The Sun formed in the center, and the planets formed in a thin disk orbiting around it.

What determines the temperature of a planet?

The surface temperature of a terrestrial planet is determined by how much energy the planet receives from the Sun and how quickly it radiates that solar energy back to space. As described in a later section, a terrestrial planet’s interior temperature is determined by its size.

How do scientists think the planets formed?

The various planets are thought to have formed from the solar nebula, the disc-shaped cloud of gas and dust left over from the Sun’s formation. The currently accepted method by which the planets formed is accretion, in which the planets began as dust grains in orbit around the central protostar.

What role did condensation temperatures play in the formation of the planets?

As the solar nebula began to rotate more rapidly, it also tended to flatten out, forming a planetary disk. In the inner part of the solar system where the temperature was high, only substances with high-condensation temperatures could become planets.

Are all planets Blackbodies?

Although a blackbody does not really exist, we will consider the planets and stars (including the earth and the sun) as blackbodies. According to the above definition, a blackbody will emit radiation in all parts of the EM spectrum, but by intuition, we know that one will not radiate in all wavelengths equally.

What is the most hottest planet in the universe?

Venus
Venus is the exception, as its proximity to the Sun and dense atmosphere make it our solar system’s hottest planet. The average temperatures of planets in our solar system are: Mercury – 800°F (430°C) during the day, -290°F (-180°C) at night. Venus – 880°F (471°C)

What are the two most important factors in temperature?

Things to remember

• The factors that affects temperature are altitude, latitude and distance from sea.
• The height measured from sea level is called altitude.
• When the latitude increases, the distant from the sun also increases, so the temperature gradually decreases.

Are planets still forming?

Planets are thought to form in a disc of dust and gas, also known as a protoplanetary disc, surrounding a host star. Theoretical models suggest planets should begin to take shape while the host star is still growing – but until now, we have only seen active evidence of planet formation …

Do Jovian planets have low density?

Despite their size, the Jovian planets have low densities because of their gaseous composition. Saturn, for example, is made of materials lighter than water. If it could be placed in a giant swimming pool, the planet would float. The Jovian planets’ colors differ due to their temperature, composition, and cloud height.
