Contact | Team Entrance | Privacy, Disclaimers, & Accessibility Mars is only about one-half the diameter of Earth, but both planets have roughly the same amount of dry land surface area. This is because over two-thirds of the Earth's surface is covered by oceans, whereas the present surface of Mars has no liquid water. Mars and Earth are very different planets when it comes to temperature, size, and atmosphere, but geologic processes on the two planets are surprisingly similar. On Mars, we see volcanoes, canyons, and impact basins much like the ones we see on Earth.

How long does it take for a signal from Earth to reach Mars? The average distance between Mars and Earth is 140 million miles. The speed of light is 186,282 miles per second. Signals travel at the speed of light, so the amount of time the signal will take to travel the average distance between the two planets is 12.5 minutes.

- One Mars day is 1 Earth day and 37 Minutes, about. One Year is 687 Earth days. Also here's some other Facts: The Diameter Of Mars is 4,223 miles (6,796 km). It has two moons. … It is on average about 142,000,000 miles from the Sun (228,000,000km). It is 60 Degrees Fahrenheit (20 Degrees Celsius), and The Atmosphere is made up of Carbon Dioxide and Nitrogen, mainly.

Why does it take 14 minutes for the information to reach Earth from Mars even though signals travel at the speed of light? Because that's how far away Mars is! The speed of light is roughly 300,000 km/second. Mars is on average about 225 million km from Earth (the distance varies greatly, depending on both planets' position in their orbits). That translates to an average distance of 12.5 light minutes. It can vary from about 4 minutes to 24 minutes, depending on Mars's current distance from Earth.

- Radio signals are electromagnetic waves, such as light or X-ray. The speed of electromagnetic waves in vacuum, is 300000km/sec (approximately). In order to calculate the time of travel with this speed from Earth to Mars, we need to know the distance. When the Mars and the Earth are at the opposite sides of the Sun, the distance is the largest: approximately: 378 million km. The time needed for an electromagnetic wave to cover this distance is approximately: 21 minute. The closest distance between Mars and Earth is 78 million km, the time in this case is: 4.3 min. So the time of travel between Earth and Mars is between 4.3 minutes and 21 minutes, depending on the actual distance between the two planets.

Astro 10: Lesson 4 Earth is only 3.6 times bigger in diameter. Mars has extreme and exaggerated surface topography because. it has less surface gravity (being a smaller planet) and less atmospheric erosion (due to its thin atmosphere) to wear down and level surface features.

- Mars's average distance from the Sun is roughly 230 million kilometres (143,000,000 mi), and its orbital period is 687 (Earth) days. The solar day (or sol) on Mars is only slightly longer than an Earth day: 24 hours, 39 minutes, and 35.244 seconds. A Martian year is equal to 1.8809 Earth years, or 1 year, 320 days, and 18.2 hours.

What are the closest and farthest distances from Earth to Mars based on their orbits around the Sun? Thanks for the A2A, Joseph Boyle. You've already gotten plenty of answers, but since they differ a bit, I may as well cast my vote. According to http://Space.com The minimum distance from the Earth to Mars is about 54.6 million kilometers. The farthest apart they can be is about 401 million km. The average distance is about 225 million km.. It's a complex question to accurately answer, because both planets follow different elliptical orbits, and those elliptical paths vary due to gravitational interaction with the other bodies in the solar system.

- First the short answer. Mars has an average distance from the Sun that is about 1.5 times that of the Earth's average distance from the Sun. This means that when Earth and Mars are closest to each other, the distance would be about 1.5 - 1.0 =0.5 times the average distance of Earth from the Sun. When Earth and Mars are on opposite sides of the Sun, the distance between would be about 1.5 + 1.0 = 2.5 times the average distance of the Earth from the Sun.

- Mars diameter is 6792 km, while Mercurys diameter is 4879 km, so Mars is bigger. Mercury is the smallest of the eight planets, Mars is the second smallest after Mercury.

Distance From Earth to Mars - How long would it take to get there? We were surprised to learn that the distance isn't actually fixed in that it depends where the planets are in their orbits. The nearest that Mars has ever been to the Earth is 56 million km or about 34.8 million miles.

What Is The Distance To Mars? The most recent conjunction, in April 2013, Mars was 364 million km away from Earth, on the other side of the Sun. And in June, 2015 it'll be 384 million kilometers. The vast distance between Earth and Mars has a real impact on our communications to the Red Planet.

Distance From Earth to Mars - How long would it take to get there? The nearest that Mars has ever been to the Earth is 56 million km or about 34.8 million miles. On the opposite end of the scale, Mars and Earth can be a whopping 401 million km (249 million miles) apart when they are in opposition and both are at aphelion. The average distance between the two is 225 million km (140 million miles).

Planet Profile No, Mars is much smaller than Earth, but both planets have similar amount of dry land. The diameter of Mars is half that of the Earth. Mars has ten percent of the mass that… the earth has. The whole surface of mars is about equal to the all of the dry land surface of the Earth.

Geodesy and the Size and Shape of the Planet Earth What makes Earth the densest of these planets however is its core. It is the only terrestrial planet with a liquid outer core that surrounds a solid, dense inner core. Earth's average density is 5515 × 10 kg/m 3. Mars, the smallest of the terrestrial planets by density, is only around 70% as dense as Earth. Earth is classified as the largest of the terrestrial planets based on its circumference and diameter as well. At the equator, Earth's circumference is 24,901.55 miles (40,075.16 km). It is slightly smaller between the North and South poles at 24,859.82 miles (40,008 km). Earth's diameter at the poles is 7,899.80 miles (12,713.5 km) while it is 7,926.28 miles (12,756.1 km) at the equator. For comparison, the largest planet in Earth's solar system, Jupiter, has a diameter of 88,846 miles (142,984 km).

Mars hoax Both Earth and Mars are in elliptical orbits around the Sun in approximately the same plane. By the nature of the laws of physics, the distance between them varies periodically from a minimum equal to the distance between their orbits at some point along them, to a maximum when they are on opposite sides of the Sun.

How Far Away is Mars? | Distance to Mars How far is Mars from Earth? On average, the distance to Mars from Earth is 140 million miles (225 million kilometers), according to NASA. However, the distance to Mars from Earth is constantly changing. Like a pair of cars on a racetrack, Mars and Earth orbit the sun at different speeds. Earth has an inside lane and moves around the sun more quickly.

The weather on Mars is both totally alien and somewhat Earth-like all at once Mars is much farther from the sun than Earth — about 142 million miles vs. our 93 million miles. Earth days and Mars days are nearly equal — one Martian sol is about 24½ hours. It takes about 687 days for Mars to revolve around the sun.

Mars The scale height of the atmosphere is about 10.8 km (6.7 mi), which is higher than Earth's (6 km (3.7 mi)) because the surface gravity of Mars is only about 38% of Earth's, an effect offset by both the lower temperature and 50% higher average molecular weight of the atmosphere of Mars.

- The average distance to Mars from Earth is 140,000,000 miles or 225,000,000 kilometers. However, this value varies because the Earth's orbit around the sun is smaller than Mars' orbit. Continue Reading

- A radio wave traveling at the speed of light takes over three minutes to cover this distance. When on opposite sides of the Sun, the distance between Earth and Mars grows considerably larger and reaches a maximum of almost 250 million miles (401 million km).
