Is it the planet Mars.
The surface of Mercury is filled with craters of all size. The planet's core makes up 42 percent of the planet's volume.
Dwarf Planet Pluto - 6,430,000 square miles of surface area.
Planet Jupiter has a surface area of 23.71 billion square miles.
Smaller objects generally cool more quickly. This is because the ratio of surface area to volume is greater for smaller bodies than it is for larger bodies. There may be other minor factors too. The most important thing though is the surface area to volume ratio.
If the smaller cells' total volume is at least that of the larger cell then the smaller cells have the greater surface area.
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
Earth's oceans cover about 70% of the planet's surface.
The surface area of planet Earth is 196.9 million square miles or 5,489,256,960,000,000 square feet.
A planet with a greater mass does not necessarily have greater surface area than one with less mass. The planet could be made of denser material and have a smaller surface area. Mass doesn't always mean volume.
Earth's surface area is about 510,072,000 km2
The surface area of Mars is 144,798,500 km2. This is about the same as all the above sea-level surface area of Earth.
148,940,000 km2 = land surface area of planet Earth
The total land area of all seven continents is approximately 148,940,000 square kilometers.
The Earth's Moon is a greyish object that has a surface area of 3.793 × 107 km² and orbits our planet
There is more water on Earth than land (surface area). Water covers nearly 71% of the Earth's surface. While Earth's surface is mostly water, Earth is nearly all rock. Just 0.5% of the planet by weight is water. -Thong Tran
Mercury is the smallest planet in the solar system, it has 7.48 (10)7 km2 of surface area (0.108 earth).
By your planet, I assume you mean the Earth. The Earth has a total surface area of 196,940,400 square miles (510,072,000 square km) and a mass of 5.9736x1024 kg.
