Mars is a planet in the solar system. It is also known as the “Red Planet” because of its red color, which is due to iron oxide and is commonly known as rust. Learn ten fascinating facts about Mars with these 7 intriguing items!
- Mars orbits between 140 million and 227 million kilometers from the sun, according to Space Math, making it roughly 147 million kilometers away from Earth on average, or 49 light minutes away.
- That means a signal sent from Earth takes 49 minutes to reach Mars! But because of their relative positions, we can see Mars much closer than this at times – when they’re both lined up so that they form an angle of less than 34.6°, according to the Mars Exploration Program.
- Mars is about half the size of Earth, notes Space Math. This means that it has about half the gravity of Earth’s gravity, which is called 0.376 g compared to 1g on Earth! You’d weigh less on Mars than you do right now on Earth!
- The average temperature on Mars is -46 °C (-51 °F) according to NASA. But despite being so cold, it does have some warmer regions where temperatures can get up to 20 °C (68 °F).
- Some scientists think that there may have been liquid water and even small oceans in Mars’ distant past, says Space Math. When we look at Mars we see many channels and other formations that look very much like the oceans’ shorelines! But Mars is thought to have lost its liquid water long ago.
- NASA and other space organizations around the world spend a lot of time looking at Mars. We want to try to find out if there were ever living things on Mars, says Space Maths. There are even ideas for astronauts to visit it in the future!
- It takes 24 hours 37 minutes and 23 seconds for Mars to spin all the way around once, according to TimeAndDate.com. That’s not anywhere near as long as it takes Earth, which spins around every 24 hours—but it’s still almost a full in length!
How Big Is Mars?
The sizes of Mars and Earth are similar. It has an equatorial diameter of around 21,000 kilometers, with a radius (the distance from the core’s middle to the surface) of roughly 3,400 kilometres. It is believed that Mars’ core is mostly made up on iron, with nickel and sulfur in moderation. The centre is about half the size of the planet and may be entirely liquid or have a solid iron interior surrounded by a liquid shell.
Olympus Mons is the solar system’s largest volcano, with a diameter of 26 kilometers. It’s approximately 25 kilometers high and 624 kilometers broad – Mauna Loa on Hawaii is 4.01 kilometres high and 120 kilometres broad. Valles Marineris, which runs for 7 kilometers deep, is the planet’s deepest canyon. Valles Marineris was mostly carved by tectonic activity.
How Hot is Mars?
On Mars, the extremely thin atmosphere produces dramatic temperature variations. When sunlight energy enters the atmosphere, it is not uniformly dispersed and readily escapes back into space. The temperature range on Mars is from -153 degrees Celsius at its poles to possible highs of 20 degrees Celsius elsewhere on the planet’s surface.
How Far From The Sun is Mars?
Mars is the fourth planet from the Sun and orbits at a distance of 228 million kilometers. The planet travels at a speed of around 24 km per second, which is somewhat slower than that of Earth (Earth’s orbital speed: 33 km per second). It has an elliptical path; this means it resembles an egg or an oval. Throughout its year, Mars’s distance from the Sun ranges between approximately 206 and 249 million kilometres.
How Long is a Day on Mars?
On Mars, a day is 24.6 hours long, similar to a day on Earth. Its years, on the other hand, are many times longer than ours: 687 days around the Sun per trip. The planet’s spin axis is tilted at 25 degrees – somewhat more than that of Earth. Due to its greater orbit around the Sun, Mars has seasons twice as long as Earth’s owing to its larger tilt of 25° in relation to its orbital position in space (compared with 27° on Earth).
How Many Light Years Away Is Mars
The distance between the planets must be worked out first in order to determine how long it will take to get to Mars. The fourth planet from the sun and second in terms of closeness (Venus is nearest). However, as they orbit around the sun, their distances from one another change.
The closest that Earth and Mars could come to each other is at their closest approach to the sun (perihelion) and farthest (aphelium). This would bring the planets a mere 33.9 million miles (54.6 million kilometers) apart, in theory. In reality, this has never happened in history. In 2003, when they were just 34.8 million miles (56 million km) apart, the two planets came as close as they had ever been documented prior on July 31st 2021 4PM GMT).
394.61 Million KM
When the two planets are at their most distant from the sun, they are on opposite sides of it. They may be 250 million miles (401 million kilometers) apart at this time. The distance between the two planets is around 140 million miles (225 million kilometers).
The Speed Of Light
The speed of light is 299,792 kilometers per second (kilometers per second). If a Martian light were to travel at that speed, it would take approximately three years to reach Earth.
In reality as per hedgethebook, the planets in their paths around the sun are never still. Engineers must calculate the best trajectories for sending a spacecraft to Mars. Their equations take into account not just distance but also fuel efficiency. This means that, in order to complete their mission, they must figure out where Earth will be when the spacecraft arrives rather than where it is now.
To avoid overshooting a new planet, spaceships must also slow down as they approach it. The distance required to get from Earth to Mars is determined by where the two planets are in their orbits when a mission is launched. It also depends on space propulsion technology advancements.
