If your planet Earth was the same distance from the Sun as Mars is would the surface of your planet be as cold as Mars is?

No. The light from the sun has to travel farther to get to Mars, so it losses more intensity than it would if it were only traveling to Earth. As a result, the sun is dimmer on Mars than it is on Earth.

∙ 15y agomars is much colder than earh is like winter all the time

∙ 14y agoProbably not. Earth has an atmosphere that can trap and hold heat very well, unlike Mars's atmosphere.

∙ 12y agoMars is colder than Earth, Mars is farther away from the sun than Earth is, so the Earth is warmer than Mars.

How would your weight change on the surface of an earth size planet whose mass was greater than earth?
It would be greater.
Why is earth known as a water planet?
Well, simply because it's currently the only planet that contains large amounts of water on its surface. Water covers more than 70% of Earth's surface, which contributes to calling our planet, the water planet.
Would a smaller planet than earth with the same shape and size have more gravity?
If the planet is smaller, then it can't have the same size. If you assume that a smaller planet has the same density as Earth (and therefore less mass), its surface gravity will be smaller. If you assume that a smaller planet has the same mass as Earth (and therefore more density), its surface gravity will be greater. This is because we would be closer to the planet's center - or to the planet's matter in general.
Why from a distance earth would be the brightest of the nine planets?
This is because sunlight is reflected by the planet's water
Is half of your planet water?
If you are referring to Earth, then the answer would be no. Approximately 70% of the Earth's surface is covered by water, and the other 30% is land.
What is the word for the distance through the center of a planet?
The distance from surface to surface through the center of a planet would be that planet's "diameter".
What would be the acceleration due to gravity of a planet that has 9.3 m earth and 4 r earth?
The acceleration due to gravity is proportional to mass and inversely proportionalto the square of distance. So, the acceleration of gravity on the surface of sucha planet, compared to that on the surface of the Earth, would be(Agrav on Earth) x (9.3/16) = 5.7 meters (18.7 feet) per second2 (rounded)
Would weight increase or decrase on the surface of an earth sized planet with greater mass than earth?
If you're the same distance from the center of the planet but its mass is greater than earth's mass, then the mutual gravitational force between you and that planet is greater than on earth, and you'll "weigh" more than you do here.
What is mean by telemetering?
To obtain and transmit measurements from a distance, usually a great distance. For example, measuring the amount of moisture on the surface of the planet Mars and sending that information back to a station on earth would be an exercise in telemetering.
How would your weight change on the surface of an Earth size planet whose mass was greater than earth's?
It would be greater.
How would your weight change on the surface of an earth-sized planet whose mass was greater than the Earth's.?
It would be greater.
How would your weight change on the surface of an earth size planet whose mass was greater than earth?
It would be greater.
How does gravity affect weight on a planet?
The importantidea here is a planet's "surface gravity". That's the measure of the planet's gravitational "pull"at its surface. The larger this number, the heavier the weight ofan object on the surface of the planet. For example, the "surface gravity" on Mars is only 38% of the Earth's. So, if you could be on the surface of Mars, your weight would be 38% of your weight on Earth.
Why would Earth be the brightest of all the 8 planets from a distance?
The Earth emits more radio waves than any other planet in our solar system due to human technology. So using a radio telescope, the Earth would appear to be the brightest planet from a distance.
Why is earth known as a water planet?
Well, simply because it's currently the only planet that contains large amounts of water on its surface. Water covers more than 70% of Earth's surface, which contributes to calling our planet, the water planet.

What would be the period of revolution for a hypothetical planet just above the surface of the sun at a distance from the solar center of 1 million km?
That would have the planet at a distance of 300,000 km from the surface. This would be in the corona region. No matter can exist in this area. At millions of degrees in temperature, everything is plasma in this area.
