Mars is the fourth planet from the Sun. The surface of Mars is orange-red because it is covered in iron (III) oxide dust, giving it the nickname " the Red Planet ". [21] [22] Mars is among the brightest objects in Earth's sky, and its high-contrast albedo features have made it a common subject for telescope viewing.
It only takes up about 15% of the Earth's volume. It would take about six Mars-sized planets to fill up the entire volume of Earth. Mars' size difference also affects the force on its surface. If ...
Geology of Mars. Generalised geological map of Mars [1] Mars as seen by the Hubble Space Telescope. The geology of Mars is the scientific study of the surface, crust, and interior of the planet Mars. It emphasizes the composition, structure, history, and physical processes that shape the planet. It is analogous to the field of terrestrial geology.
Old Mars logo used between the company's founding in 1911 until March 2019. Mars is a company known for the confectionery items that it manufactures, [14] such as Mars bars, 3 Musketeers, Milky Way bars, M&Ms, Skittles, Snickers, Twix, and Bounty (chocolate bar) . It also produces non-confectionery snacks, such as Combos, and other foods ...
Climate of Mars. Mars' cloudy sky as seen by Perseverance rover in 2023, sol 738. The climate of Mars has been a topic of scientific curiosity for centuries, in part because it is the only terrestrial planet whose surface can be easily directly observed in detail from the Earth with help from a telescope .
Tracking Mars’ wobble, or nutation, enabled the team to measure the size of the core. The RISE data suggested the core has a radius of about 1,140 miles (1,835 kilometers).

Mars-1 was the first spacecraft launched to Mars in 1962, but communication was lost while en route to Mars. With Mars-2 and Mars-3 in 1971–1972, information was obtained on the nature of the surface rocks and altitude profiles of the surface density of the soil, its thermal conductivity, and thermal anomalies detected on the surface of Mars.
