## How long does it take a geostationary satellite to complete one orbit?

1,436 minutes

## How do you calculate the orbital speed of a satellite?

The orbital speed can be found using v = SQRT(G*M/R). The R value (radius of orbit) is the earth’s radius plus the height above the earth – in this case, 6.59 x 106 m.

**Do really 90 minutes the satellites circle the Earth?**

To stay in orbit, a satellite has to travel at a very high velocity, which depends on the height. At this speed, the satellite will complete one orbit around the Earth in 90 minutes. Satellites have to move so quickly in order to compensate for the pull of Earth’s gravity.

**How is ISS speed calculated?**

To calculate the speed (velocity) of the ISS orbiting around the Earth, we need to treat it like a satellite. 2. The formula is: Square root of ((Gravitational constant x Mass of Earth) Radius of the ISS from the center of the Earth). Units must be in metric, specifically in meter, kilogram, second.

### What’s the speed of ISS?

7.66 km/s

### At what speed do satellites orbit the earth?

about 11,000 kilometers per hour

**Do satellites run out of fuel?**

Satellites do carry their own fuel supply, but unlike how a car uses gas, it is not needed to maintain speed for orbit. It is reserved for changing orbit or avoiding collision with debris.

**How long can a satellite stay in orbit?**

The satellites in the very low end of that range typically only stay up for a few weeks to a few months. They run into that friction and will basically melt, says McDowell. But at altitudes of 600 km—where the International Space Station orbits—satellites can stay up for decades.

#### What is the lowest orbit possible?

There is an orbit around the Earth called the Low Earth orbit (LEO) with an altitude between 160-2000 km. This is the lowest altitude at which an object can go on orbiting around the Earth.

#### What are the three types of orbits?

There are essentially three types of Earth orbits: high Earth orbit, medium Earth orbit, and low Earth orbit. Many weather and some communications satellites tend to have a high Earth orbit, farthest away from the surface.

**How far away is space in feet?**

In the US, “space” begins at 80.4km (50 miles), or 264,000 feet. General international consensus sets a similar limit for the start of space as 100km (62 miles), or 380,000 feet. “Low Earth Orbit” (LEO), where many satellites live, goes from 160km (100 miles, 525,000 feet) to 2,000km (1,240 miles, 6.5 million feet).

**How far up is Orbit?**

At an altitude of 150 miles (242 kilometers) above Earth, orbital velocity is about 17,000 miles per hour.

## Does space have end?

No, they don’t believe there’s an end to space. However, we can only see a certain volume of all that’s out there. Since the universe is 13.8 billion years old, light from a galaxy more than 13.8 billion light-years away hasn’t had time to reach us yet, so we have no way of knowing such a galaxy exists.

## What happens if you don’t have a suit in space?

What would happen if you went to space without a spacesuit? The vacuum of space will pull the air from your body. So if there’s air left in your lungs, they will rupture. Oxygen in the rest of your body will also expand.

**How many times does a satellite orbit the Earth in a day?**

They orbit exactly over Earth’s equator and make one orbit per day. Thus, since Earth rotates once on its axis per day, the GOES satellite seems to hover over the same spot on Earth all the time.

**How many dead satellites are in space?**

There are estimated to be over 128 million pieces of debris smaller than 1 cm (0.39 in) as of January 2019. There are approximately 900,000 pieces from one to ten cm. The current count of large debris (defined as 10 cm across or larger) is 34,000.

### How many satellites are circling the Earth?

2,200 satellites

### Which country has the most satellites?

the USA

**Which country reached Mars first?**

India

**How many satellites does USA have?**

1,425
