What is a good estimate for the diameter of Mars?

Diameter and circumference At its equator, Mars has a diameter of 4,222 miles (6,794 km), but from pole to pole, the diameter is 4,196 miles (6,752 km). Mars’ radius is, of course, half of planet’s diameter.

What is the radius of Mars compared to Earth?

Bulk parameters

What method can be used to determine the distance of Mars from Earth?

Parallax
Astronomers estimate the distance of nearby objects in space by using a method called stellar parallax, or trigonometric parallax. Simply put, they measure a star’s apparent movement against the background of more distant stars as Earth revolves around the sun.

What is the actual estimated time for a journey to Mars from Earth?

The total journey time from Earth to Mars takes between 150-300 days depending on the speed of the launch, the alignment of Earth and Mars, and the length of the journey the spacecraft takes to reach its target. It really just depends on how much fuel you’re willing to burn to get there. More fuel, shorter travel time.

How much gravity is there on Mars compared to Earth?

What is Mars like compared to Earth?

In short, compared to Earth, Mars is a pretty small, dry, cold, and dusty planet. It has comparatively low gravity, very little atmosphere and no breathable air. And the years are also mighty long, almost twice that of Earth, in fact.

What method can be used to determine the distance of Mars from Earth Brainly?

Using triangulation, Cassini was able to make a measurement of the distance to Mars.

How do you measure the distance between Mars and the Sun?

Mars orbits the Sun at an average distance (semi-major axis) of 228 million km (141.67 million mi), or 1.524 astronomical units (over one and a half times the distance between Earth and the Sun).

How long does it take to get to Mars from Earth at the speed of light?

Traveling At the Speed of Light Towards Mars If you were to travel at the speed of light, which is around 300,000 kilometers per second or 186,000 miles per second in a vacuum, you would reach Mars at its closest possible approach to Earth in just 3.03 minutes, or 182 seconds.

How long does it take a message to travel from Earth to a spacecraft at Mars at its closest to Earth?

Earth’s average distance from the Sun is 1,496·108 km and Pluto’s average distance is 5.916 · 109 km. If we assume the two planets are lined up on the same side of the Sun, the average distance between them is: Earth to Pluto distance = 5.916 · 109 km − 1.496 · 108 km = 5.766 · 109 km.

What is the radius of Mars in km?

2,106.1 mi
Mars/Radius

How do you determine the magnification of a telescope on Mars?

You get this based on the focal length of the telescope and that of the eyepiece you’re using. Magnification = telescope’s focal length ÷ the eyepiece’s focal length. Mars is a small object and contrast is not an issue so you can go full throttle with the magnification.

How far away is Mars from Earth?

At that time, the distance between Earth and Mars was less than 35 million miles—the closest they have been to one another in 60,000 years! Mars grew to an impressive 25” in apparent diameter and was at its brightest magnitude, -2.8! For comparison, during a non-favorable opposition year, Mars can be as far as 62 million miles from Earth.

What is the mass of 10 10 km3 on Mars?

Ratio. (Mars/Earth) Mass (10 24 kg) 0.64171. 5.9724. 0.107. Volume (10 10 km 3) 16.318. 108.321.

What is the total surface area of Mars?

Surface Area. The sum of the areas of all shapes that cover the surface of the planet. About 28\% that of Earth. Mars: 144,371,391 square kilometers (1.4437 x 10 8 km 2) or 55,742,106 square miles. Earth: 510,064,472 square kilometers (5.1006 x 10 8 km 2) or 196,936,994 square miles. Bulk. Volume.
