Mars' axis of rotation is tilted 25 degrees with respect to the plane of its orbit around the Sun. This is another similarity with Earth, which has an axial tilt of 23.4 degrees. Like Earth, Mars has distinct seasons, but they last longer than seasons here on Earth since Mars takes longer to orbit the Sun (because it's farther away).

Planet type: terrestrialRadius: 3,396 kmMass: 6.417 × 10^23 kgAphelion: 249.2 million km (154.9 million miles)Mars is the second smallest planet in the Solar System – only Mercuryis smaller. Let’s measure this planet and compare it to the Earth.
Every planet in the Solar System has its own orbital period (that determines the length of year) and rotation period (that determines the length of a day-night cycle). Let’s take a look at how fast Mars revolves around the Sun and spins on its axis.
Mars is the fourth planet from the Sun and one of the Earth’s two closest neighbors (the other one being Venus).
As the Earth’s close neighbor, Mars has been the destination of numerous space missions. Since 1960, about 50 missions have been sent to the Red Planet, though only about half of them have been successful. Let’s take a look at the most significant ones. NASA’s Mariner 9entered Mars’ orbit in 1971, becoming the first spacecraft to orbit another plan...
Like the other three terrestrial planets (Mercury, Venus, and the Earth), Mars is a rocky celestial body. Let’s take a closer look at the planet’s physical peculiarities.
Mars has two moons: Phobos and Deimos. Both of them were discovered by American astronomer Asaph Hall in 1877. The moons of Mars are among the smallest moons in the Solar System: for reference, the Earth's Moon has a diameter more than 100 times greater than that of Phobos, the larger Martian moon. Like our Moon, Phobos and Deimos are tidally locke...
November 20: Mars near the Moon
1. Conjunction time: 21:07 GMT (4:07 p.m. EST) 2. Conjunction distance: 2°36' 3. Close approach time: 22:15 GMT (5:15 p.m. EST) 4. Close approach distance: 2°20' On November 20, the 77%-illuminated Moon and Mars (mag 0.2) will meet in the constellation Cancer. The planet will rise in the evening and will be visible to the naked eye.
December 3: Mars near the Beehive Cluster
On December 3, at 12:08 GMT (7:08 a.m. ET), the planet Mars (mag -0.5) will meet the Beehive star cluster (mag 3.1) — the objects will pass within 1°36' from each other. The objects will be easily visible to the naked eye. Mars will be a month away from its opposition, already shining bright and high in the sky. To get a more detailed view of the celestial duo, use a pair of binoculars.
December 18: Mars near the Moon; lunar occultation of Mars
1. Occultation start: 07:47 GMT 2. Occultation end: 10:48 GMT 3. Conjunction time: 08:46 GMT 4. Conjunction distance: 1°00' 5. Close approach time: 09:13 GMT 6. Close approach distance: 0°52' On December 18, the 90.9%-illuminated Moon and Mars (mag -0.9) will meet in the constellation Cancer; the Beehive star cluster will also shine nearby. The planet will rise in the evening and will be visible to the naked eye. Also, a lunar occultation of Mars will be visible over Canada, Greenland, easter...
What is the gravity on Mars?
The gravity on Mars is 62% lower than on the Earth. This means that a person who weighs 80 kg (176 lbs) on our planet would weigh only 30 kg (66 lbs) on Mars. Although it would be much easier for humans to walk on Mars, such low gravity can have other not-so-pleasant effects on hypothetical Mars colonists – like causing muscle deterioration and osteoporosis.
What color is Mars?
The predominant color of the Martian surface is red. It is explained by the prevalence of iron oxide – more commonly known as rust – in the planet’s soil. Other colors on Mars include golden, brown, and tan.
What is the temperature on Mars?
Overall, Mars is a very cold place. The average temperature on the Red Planet equals -62 °C (-81°F). However, according to Michael Mischna, a research scientist at NASA’s Jet Propulsion Laboratory, the air temperature on Mars wouldn’t feel the same as on the Earth. There’s little water vapor and few air molecules on Mars, so -70 °C (-100 °F) would feel like -34 °C (-30 °F). To better understand temperature conditions on Mars, check this infographic made by NASA.
Sep 29, 2020 · At its farthest point from us, you would reach Mars traveling with the speed of light in just 22.4 minutes / 1,342 seconds. At its average distance away from us, the destination towards Mars at the speed of light would take you only 12.5 minutes / 751 seconds.
Jun 9, 2023 · The best estimates are that human missions to Mars will be timed to take advantage of a good planetary alignment. Most estimates put the travel time in the range of 150-300 days – that's five to 10 months – and the average is usually around seven months, just like the Perseverance rover.
