In 2003, the Hubble Space Telescope captured this image of the Red Planet 11 hours before it made its closest approach to Earth in 60,000 years. How close? It was only 34,648,840 miles (55,760,220 km) away. The next closest approach will be in 2287.
Which Is Known As The Red Planet
The red planet Mars, named after the Roman god of war, is an omen in the red sky. And in its own way, the planet’s rusty surface tells a story of destruction. Billions of years ago, the fourth planet from the Sun may have been mistaken for Earth’s smaller twin, with liquid water on its surface and possibly even life.
The Solar System.
Now the world is a cold, barren desert, with only a few feet of liquid water. But after decades of study using orbiters, landers and pirates, scientists discovered a dynamic, windy Martian region that could still harbor microbial life beneath the crust today.
With a radius of 2,106 miles, Mars is the seventh largest planet in our solar system and about half the diameter of Earth. Its surface gravity is 37.5 percent of Earth’s.
Recent NASA exploration missions have revealed some of the Red Planet’s greatest mysteries. This video explains what is different on Earth and what would happen if humans lived there.
Mars rotates on its axis every 24.6 Earth hours, determining the length of a Martian day, called a sol (short for “solar day”). The axis of rotation of Mars is 25.2 degrees relative to the plane of the planet’s orbit around the Sun, which helps Mars to have the same periods as Earth. Whichever hemisphere is closest to the Sun experiences spring and summer, while the opposite hemisphere is removed, autumn and winter. At specific moments called the equinoxes every two years, both hemispheres receive equal light.
Planets Of The Solar System
But the seasons on Mars are very different from those on Earth. For one, Mars is on average 50 percent farther from the Sun than Earth, with an average orbital distance of 142 million miles. This means that Mars takes a long time to complete one orbit, the length of its years and seasons. A year on Mars lasts 669.6 sols, or 687 Earth days, and a single period lasts over 194 sols, or 199 Earth days.
The angle of Mars’ axis of rotation also changes more frequently than Earth’s, which has caused the Martian climate to change over thousands of years. In addition, Mars’ orbit is less circular than Earth’s, which means that its orbital velocity varies greatly over the course of a Martian year. This annual variation of Red Leo affects the solstices and equinoxes of the planets. On Mars, spring and northern summer are longer than fall and winter.
Another complicating factor: Mars has a much thinner atmosphere than Earth, which dramatically reduces how much heat the planet can absorb near its surface. Mars’ surface temperatures can reach as high as 70 degrees Fahrenheit and as low as -225 degrees Fahrenheit, but on average its surface is -81 degrees Fahrenheit, a full 138 degrees cooler than Earth’s average temperature.
The main driver of modern Mars geology is its atmosphere, which is composed mainly of carbon dioxide, nitrogen and argon. Signs through the earth, ahead the air is thin; The air pressure on Mount Everest is about 50 times higher than on the surface of Mars. Although the winds are thin, Martian winds can blow up to 60,000 kph, raising dust that covers large dust storms and vast, sandy desert plains.
Which Planet Is Known As The Red Planet?
Once, however, wind and water flowed to the Red Planet. Robust robotics has found clear evidence that lakes and rivers of liquid water flowed across the Red Planet’s surface billions of years ago. This means that at some point in Mars’ past, the atmosphere was dense enough and hot enough for water to remain liquid on the Red Planet’s surface. Not so today: Although water ice is abundant beneath the surface of Mars and on the polar caps, there are no large bodies of liquid water on the surface today.
Mars also lacks an active tectonic system, the geological engine that powers our Earth, and it also lacks a planetary magnetic field. The lack of this protective barrier makes it easier for particles from the Sun to penetrate the Red Planet’s atmosphere, which may help explain why Mars’ atmosphere is so thin. But in the ancient past—from about 4.12 to 4.14 billion years ago—Mars appears to have had an internal dynamo that could have largely powered the planet’s magnetic field. Does Dynamon March stop? Scholars also try to figure it out.
Like Earth and Venus, Mars has mountains, valleys, and volcanoes, but it is the largest and most dramatic of the Red Planets. Mount Olympus, the largest volcano in the solar system, is about 16 miles above the surface of Mars, making it three times higher than Mount Everest. But the base of Mount Olympus is so wide—about 374 miles across—that the volcano’s slope is only slightly higher than the rim of the wheel. Such a large peak, the surface of Mars is curved. If you stood on top of Mount Olympus, its peak would be beyond the horizon.
Mars has not only the highest altitudes, but also the lowest altitudes in the solar system. Southeast of Mount Olympus is the Valley of the Mariners, the Red Planet’s iconic canyon system. It cuts a distance of about 2,500 miles and 4.3 miles across the Red Planet’s surface. The canyon network is four times deeper and five times longer than Earth’s Grand Canyon, and is 200 miles at its widest point. The valleys are named after Mariner 9, which became the first spacecraft to orbit another planet when it reached Mars in 1971.
Mars Is Also Known As The ‘red Planet’ Because, Well, It’s Red!
About 4.5 billion years ago, Mars coalesced from a gaseous, dusty orb that surrounded the young Sun. Over time, the red intestine divides into a core, a covering, and an outer layer that is an average of 40 miles thick.
Its core is made of the same iron and nickel, but probably contains more sulfur than ours. The best available opinions suggest that the core is about 210 miles, give or take 370 miles – but we don’t know the specifics. NASA’s Probe Lander aims to uncover the secrets of Mars’ interior as seismic waves travel across the Red Planet.
Septemtrinal Mars and the southern hemispheres of Bacchus are distinct from each other, unlike any other planet in the solar world. The planet’s northern hemisphere has mostly low plains, and its crust may be only 19 miles thick. But the Southern Hemisphere’s southern mountains are the stubs of many extinct volcanoes, and the crust there can be up to 62 miles thick.
What happened It is possible that internal magma flow patterns caused the variation, but some scientists believe that the Martian event experienced one or more major moments. A recent model of Mars suggests it has two faces because the shape of Earth’s moon pushed Mars toward its south pole.
Hey Martian, Say Cheese
Both hemispheres have one thing in common: they are covered in planetary dust, which takes on many shades of orange, red and iron rust.
At some point in the past, the Red Planet acquired two small and irregularly shaped moons, Phobos and Deimos. The two lumpy worlds, discovered in 1877, are named after the sons and drivers of the god Mars in Roman mythology. How the Moon was formed remains unresolved. One possibility is that they formed in the asteroid belt and were captured by the gravity of Mars. But recent models suggest instead that they may have formed from debris on Mars a long time ago.
Deimos, the smaller of the two moons, orbits Mars every 30 hours and is less than 10 miles away. Its older brother Phobos bears many scars on its surface, including deep pits and furrows. For a long time, scholars debated what the striations on Phobos were. Are the tracks left by the rocks rolling across the surface after an ancient impact, or are there signs that Mars’ gravity pulled the moon?
Either way, the moon’s future will be a little less bleak. Every century Phobos approaches Mars by about six feet; In 50 million years or so, the moon is predicted to either crash into the Red Planet’s surface or break into smithereens.

Since the 1960s, humans have robotically explored Mars more than any other planet outside of Earth. Eight missions from the US, the European Union, Russia and India are currently operating on Mars or orbiting its surface.
