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. Although Mars is smaller than the Earth ...
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 ". [22][23] 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.
List of hottest exoplanets. This is a list of the hottest exoplanets so far discovered, specifically those with temperatures greater than 2,500 K (2,230 °C; 4,040 °F). For comparison, the hottest planet in the Solar System is Venus, with a temperature of 737 K (464 °C; 867 °F).
A planetary core consists of the innermost layers of a planet. [1] Cores may be entirely liquid, or a mixture of solid and liquid layers as is the case in the Earth. [2] In the Solar System, core sizes range from about 20% (the Moon) to 85% of a planet's radius (Mercury). Gas giants also have cores, though the composition of these are still a ...
έήΏύΓ. The atmosphere of Mars is the layer of gases surrounding Mars. It is primarily composed of carbon dioxide (95%), molecular nitrogen (2.85%), and argon (2%). [3] It also contains trace levels of water vapor, oxygen, carbon monoxide, hydrogen, and noble gases. [3][5][2] The atmosphere of Mars is much thinner and colder than Earth's ...

September 5, 2024 at 10:00 PM. Summer broke global heat records for the second straight year, scientists have confirmed — putting 2024 firmly on track to be the hottest year in recorded history ...
Venus is the hottest planet, with surface temperatures over 400 °C (752 °F), mainly due to the amount of greenhouse gases in the atmosphere. [98] The planet lacks a protective magnetic field to protect against stripping by the solar wind, which suggests that its atmosphere is sustained by volcanic activity. [99]
