Let's calculate that. First of all we know that in general, the time it takes to travel a distance is equal to the length of that distance, divided by the speed at which you travel that distance. If we reverse that, we get that the speed is equal to the distance traveled over the time taken.
We also know that the time it takes for the Earth to go once around the Sun is 1 year. So in order to know the speed we just have to figure out the distance traveled by the Earth when it goes once around the Sun. To do that we will assume that the orbit of the Earth is circular (which is not exactly right, it is more like an ellipse, but for our purpose it will do just fine). So the distance traveled in one year is just the circumference of the circle. (remember that the circumference of a circle is equal to 2*pi*Radius)
The average distance from the Earth to the Sun is 149,597,890 km. Therefore in one year the Earth travels a distance of 2*Pi*(149,597,890)km. This means that the velocity is about:
velocity=2*Pi*(149,597,890)km/1 year
and if we convert that to more meaningful units (knowing there is 365 days in a year, and 24 hours per day) we get:
velocity=107,300 km/h (or if you prefer 67,062 miles per hour)
So the Earth moves at about 100,000 km/h around the Sun (which is 1000 times faster than the speeds we go at on a highway!)
The earth moves around the sun in a elliptical orbit.
The moon does orbit the Sun. Locked in orbit around the Earth, as the Earth orbits the Sun, the moon orbits the Sun.
No, Mars does not orbit around the Earth. The moon orbits around around the Earth. Both Earth and Mars orbit around the sun, but Mars is farther away from the sun.
Mars travels around the sun at a little over 54,000 mph and completes an orbit in roughly 687 Earth days
No. The moon's orbit is tilted by about 5 degrees relative to Earth's orbit around the sun. This is why we do not see eclipses every month.
It would need to be launched into a tangent plane parellel to that of the earth's orbit around the sun, with the same speed of rotation around the sun
It takes 87.97 earth days to orbit around the sun.
The earth moves around the sun in a elliptical orbit.
The moon does orbit the Sun. Locked in orbit around the Earth, as the Earth orbits the Sun, the moon orbits the Sun.
The speed of Earth is related to the position of its orbit around the Sun. At a higher speed, Earth would need to be closer to the Sun; at a lower speed, it would need to be farther from the Sun. In its current orbit, Earth moves around the Sun at a speed of about 30 km/second. Earth can't get much closer to the Sun (and therefore move faster) than that; for instance, Venus moves around the Sun at a mean speed of about 35 km/second, and it seems that Venus is too close to the Sun for life.
No, the earth revolves around the sun.
