Planet Mars

Mars' year is 687 Earth days long because it takes that amount of time for the planet to complete one orbit around the Sun. Mars is farther from the Sun than Earth, so it travels a greater distance in its orbit, resulting in a longer year.

The Tharsis bulge is a vast volcanic plateau on Mars that rises about 5 miles (8 kilometers) above the surrounding plains. It is home to some of the largest volcanoes in the solar system, including Olympus Mons, which is the tallest volcano in the solar system. The Tharsis region is thought to have contributed to the planet's tectonic activity and may have influenced the planet's climate and geological history.

No, firstly because neither planet really existed at that time (they were barely forming from the disc of debris orbiting the sun - protoplanets) and also Mars has always been right about where it is now, in orbit around the Sun. If Mars had collided with the Earth long ago, there is no force in nature that could have put it into the orbit it now has. But 4 billion years ago, there were probably dozens of other "baby planets" wandering around the solar system, interacting via gravity with each other. Back then , collisions were probably relatively common. Something - probably not quite as big as Mars, but perhaps close - probably DID collide with the proto-Earth, smashing an enormous chunk out of it. The debris from the collision, both from Earth and from that "other planet", then coalesced to form the Moon.

The sky on Mars appears butterscotch-colored during sunset due to the dust particles in the atmosphere scattering light in a way that creates this unique coloring.

A light-year is not a measurement of time but of distance. How far light can travel in a year. Your question therefore asks about the distant between the Earth and Mars which varies with their orbiting about the sun.. However, Earth and Mars are never anywhere near a light year abart. At most, they are about 12 light minutes apart.

Yes, Mars has been explored by several satellites and spacecraft. Missions like NASA's Mars Reconnaissance Orbiter and the Mars rover missions, such as Curiosity and Perseverance, have provided valuable data and images of the planet's surface. These missions have helped scientists study Mars' geology, atmosphere, and potential for past or present life.

Phobos, one of the moons of Mars, orbits the planet at a speed of about 2.14 km/s (4,800 mph). It is one of the fastest-moving moons in the Solar System due to its close proximity to Mars.

Well, we can assume so, at least with the aided eye. Phobos and Deimos, the two moons of Mars, can easily be seen from Earth with the correct telescope, so it would be even easier on Mars, with less atmosphere and a shorter distance.

You would be the same age, of course.

However, you probably mean how old you would be in "Mars years".

There are two ways to calculate this:

A Mars year is 686.98 Earth days. At nine Earth years old, you are 3287.25 Earth days old.

Divide that by 686.98 and you get 4.7850738 Mars years old.

A Mars year equals approximately 1.88 Earth years. So, nine divided by 1.88 equals 4.78723404.

The former is a bit more accurate. You would be 4 3/4 rounded to the nearest quarter.

Mars rotates on its axis in 24.6 earth hours = 1.025 earth days.

Mars has a very thin atmosphere with a pressure of .636 kPa. It is composed of 96 percent carbon dioxide with trace amounts of argon, nitrogen, oxygen and carbon monoxide.

You can find facts about Mars from reputable sources such as NASA's website, scientific journals, and books written by space experts. These sources provide detailed and accurate information about Mars, its features, exploration missions, and ongoing research findings.

The two machines that have landed on Mars are the Perseverance rover, which landed in February 2021, and the Curiosity rover, which landed in August 2012.

Mars has two small moons named Phobos and Deimos. Phobos is the larger of the two moons and orbits very close to Mars, while Deimos is smaller and orbits further away. Both moons are thought to be captured asteroids.

Mars' atmosphere is mostly carbon dioxide with trace amounts of other gases, but it does not contain any toxic gases that would pose a threat to visitors. However, the thin atmosphere and lack of oxygen make it inhospitable to human life without life support systems.

Mars has low atmospheric pressure because its gravity is weaker than Earth's, which means it can't hold on to its atmosphere as effectively. Additionally, Mars likely lost a significant amount of its atmosphere over time due to factors like the solar wind and lack of a strong magnetic field.

Mars is weaker than Earth in terms of physical strength due to its smaller size and lower gravity. However, in terms of geological processes, Mars can be considered stronger as it has evidence of past volcanism, tectonic activity, and large-scale water flow.

If you are wondering what the "red planet" is, it is the planet called~ Mars.

Mars is visible from Earth because both planets orbit the Sun. When Mars aligns with Earth in its orbit, it can be seen in the night sky. Additionally, Mars reflects sunlight back towards Earth, making it visible to the naked eye.

Mars has two ice caps. Planum Australe (Southern) and Planum Boreum (Northern). See links for further information.

Dust storms on Mars can reach sizes covering entire regions or even the entire planet, with some storms reaching heights of up to 60 kilometers (37 miles). These storms can last for days, weeks, or even months, and their intensity can vary depending on factors like the season and local conditions.

The polar ice caps of Mars are believed to consist mostly of water ice and carbon dioxide ice, also known as dry ice. The northern polar cap is composed mainly of water ice, while the southern polar cap has a mixture of water ice and dry ice. These ice caps play significant roles in the planet's climate and seasonal changes.

We know the specific answers to specific questions that the probes were designed to find out. There have been several Mars landers, starting with two Viking probes that landed on July 20, 1976. (The first one was supposed to land on July 4, 1976 on the Bicentennial day - but there were Martian duststorms that lasted for weeks. So it landed on the anniversary of the Apollo 11 landing on the Moon.)

Then the Mars Rover landed in the 1990's, and then two more - Spirit and Opportunity - five years ago. Between the satellite photography and the landers, we learned a LOT about Mars from our robot probes.

That is called "tides".

__________________________

Sort of. The Moon doesn't really orbit the Earth. Rather, the Earth and the Moon BOTH orbit the "common center of mass" of the Earth/Moon system. That common center of mass is inside the Earth, but not AT the center of the Earth. (If the common center of mass or 'center of gravity' were outside the Earth and somewhere in between the Earth and the Moon, then technically the Moon wouldn't be a "moon"; it would be a co-planet with Earth.)

Tides are actually caused by the fact that the water on the far side of the Earth and the water on the near side of the Earth (with respect to the Moon) are technically in the "wrong" orbits around the Moon. Remember, gravity goes both ways! The water on the far side of the Earth is orbiting too fast and should move into a higher orbit; the water on the near side is orbiting too slowly and should fall into a lower orbit, from the perspective of the Moon. Because the Earth's gravity is much stronger than the Moon's gravity, the effects are actually quite small.
