Scientists have discovered a new planet. The planet is in a solar system whose star is similar in size to the sun and is about as far from the star as Venus is from the sun. The planet is similar in size to Earth, and its atmosphere is similar in thickness to Earth’s atmosphere. The atmosphere is composed almost entirely of carbon dioxide and methane.

In three to five sentences, make a hypothesis about the temperature on the planet’s surface. Explain your answer using information about the planet’s location and atmosphere.

I think the temperature might be somewhere between 59 degrees fahrenheite. But it could be -200 or somethingb like that since venus is one of planets farthest from the sun. And It probaly holds life on the surface therefore showing the temperature is around 59 or somewhere in that range. Hope this helps

The temperatures of such a planet would most probably be higher than 450°C.

The planet will be quite hot because:

proximity to the sun: it is quite clos to the sun which means that a lot of heat will reach the planet from the sun and make it as hot as Venus and Mercury.

atmospheric composition - the atmosphere is made up of carbon dioxide and methane which are both greenhouse gases. Greenhouse gases have a tendency to trap the sun's heat in a planet so the heat that will come from the sun will be trapped in the planet and make it hotter.

Venus in our solar system has surface temperatures of about 475°C and is the hottest planet in the solar system. It also has a carbon dioxide filled atmosphere.

Drawing from the similarities the planet has with Venus and how hot Venus is, we can conclude that the planet will have temperatures close to or more than that of Venus.
