How fast do you have to go to maintain Earth orbit?

This really depends on what you mean by “into space.” If you just want to get into orbit around the Earth, you need to reach speeds of at least 4.9 miles per second, or about 17,600 miles per hour.

How long does it take for an object in low Earth orbit to orbit the Earth?

LEO systems orbit the earth at altitudes ranging from about 700 to 3000 km, and unlike GEOs, move with respect to the earth. A typical LEO satellite orbits the earth in less than two hours, which means that a satellite is in view for only a few minutes.

How fast can spacecraft travel?

It is about 4.25 light-years away, or about 25 trillion miles (40 trillion km). The fastest ever spacecraft, the now- in-space Parker Solar Probe will reach a top speed of 450,000 mph.

What is the range of altitude of a low earth orbit What are the applications of LEO satellites?

LEO satellites orbit between 2,000 and 200 kilometers above the earth. LEO satellites are commonly used for communications, military reconnaissance, spying and other imaging applications.

How far can an astronaut travel in space?

That ~18 billion light-year figure is the limit of the reachable Universe, set by the expansion of the Universe and the effects of dark energy.

What is the fastest speed of a spacecraft?

NASA solar probe becomes fastest object ever built as it ‘touches…

• Fastest human-made object: 244,255 mph (393,044 km/h).
• Closest spacecraft to the sun: 11.6 million miles (18.6 million kilometers).

How fast does a spacecraft travel to the moon?

Beyond Earth Stage three fired twice – once to get Apollo into orbit – and then again to propel the spacecraft away from Earth towards the moon at a speed of 25,000mph.

What is the distance from the center of the Earth to gravity?

Earth has a radius of 6.38×10 6 m, and a mass of 5.98×10 24 kg, now since the spacecraft is two earth radii above the surface of the earth, it is three earth radii from the center , which is the distance you want to use in the formula for gravity. So now we know that the center to center distance is 3 (6.38×10 6 m) = 1.914×10 7 m

Why can’t we put a satellite in an orbit around 45th parallel?

That is the orbits of all satellites lie in a plane. That planemust pass through the centerof Earth. So we can notput a satellite in an orbit that cuts through the 45th parallel.

What is the centripetal acceleration of a spaceship with 5G?

Assume the spaceship’s diameter is 32 m, and give your answer as the time needed for one revolution. Well, .5 g is .5 (9.8 m/s/s) = 4.9 m/s/s. This is what you want the centripetal acceleration to be it you want a half a “g” of artificial gravity.

What is the acceleration due to gravity on a hypothetical planet?

A hypothetical planet has a radius 2.5 times that of Earth, but has the same mass. What is the acceleration due to gravity near its surface? We don’t really have an IB formula for the acceleration of gravity on the surface of a planet, but we know that F = ma, so the acceleration of an object with mass m is: a = F/m.
