The core of Mars is cooler than the Earth. Why

depends on the surface area relative to the volume of a planet.

A larger planet like Earth has a lot of volume and a limited amount

of surface area by which to radiate its internal heat to space.

Mars is smaller but has more surface area per volume than Earth,

so it can radiate its internal heat away to space more efficiently

than Earth. There are other smaller differences in the initial

heat of accretion and the heat released when the core forms from

an initially homogeneous mass, but the surface area is the biggest

factor.

like none of this has an actual temperature

What is the central temperature of Mars?

The central temperature of Mars is estimated to be around 1,600-2,300 degrees Celsius (2,900-4,200 degrees Fahrenheit). This high temperature is due to the heat left over from the planet's formation and radioactive decay in its core.

How hot is Mars inner core?

The temperature of Mars' inner core is estimated to be around 1,800-2,500 degrees Fahrenheit (1,000-1,400 degrees Celsius), similar to Earth's inner core. This heat is generated from the residual heat from the planet's formation and radioactive decay of elements within the core.

What planet has iron?

Iron is found on many planets in our solar system, including Earth, Mars, and Mercury. However, the abundance and distribution of iron may vary from planet to planet. For example, iron is a major component of Earth's core, while on Mars, iron is present in the planet's soil and dust.


What planet is the coldest planet and why?

Uranus is the coldest planet. Neptune is the furthest from the Sun, but it has a much hotter core temperature than Uranus; Neptune's core is at around 7000 °C. Uranus's core's temperature is at around 4737 °C.

Which planet is denser Mars or Earth?

Earth is more dense than Mars because of its huge iron core, which is larger than the planet Mars (if you include both the inner and outer core). Earth's average density is about 5.5 g/cm3, compared to 3.9 g/cm3 for Mars.
