What Are the Different Earth Orbits? | Neil deGrasse Tyson Explains…

What are the different Earth orbits? On this explainer, Neil deGrasse Tyson and Chuck Nice explore getting into orbit, what each level of orbit means, and how they are used. Also, how would a space elevator work?
What is a geosynchronous orbit? Geostationary? We discuss how Isaac Newton figured out the speed an object would need to get into orbit. What is low Earth orbit versus middle Earth orbit? The answer, we promise, has nothing to do with the presence of hobbits. Learn about plans to create an elevator to space. Why would it be useful and how could we do it? Plus, what would the space elevator music be?

Our World was the first live, international, satellite television production, which was broadcast on 25 June 1967. Creative artists, including the Beatles, opera singer Maria Callas, and painter Pablo Picasso - representing nineteen nations - were invited to perform or appear in separate segments featuring their respective countries. The two-and-a-half-hour event had the largest television audience ever up to that date: an estimated 400 to 700 million people around the globe watched the broadcast. Today, it is most famous for the segment from the United Kingdom starring the Beatles. They performed their song "All You Need Is Love" for the first time to close the broadcast.

There's also the Molniya orbit, that allows you to approximate geostationary for high latitudes; polar orbit, that allows you to see the Earth's entire surface; and sun-synchronous orbit, that's almost a polar orbit but allows your satellite to always be in sunlight. That last is a popular one these days, which is why we're starting to see more high-latitude launch sites in places like Alaska and Scotland. The fourth country that tested an antisat was India.

8:02 A geosynchronous orbit also has a period of one sideral day like the geostationary orbit. The difference is that the geostationary orbit is a circle over the equator (i.e. it has an angle of 90° with respect to the Earth's axis), whereas geosynchronous orbits can be circles as well as elipses with any angle.

Telstar was not a synchronous satellite.

I worked at Hughes Aircraft Co. at the time that their company financed Syncom 1 was launched, making ATT's Bell Labs scheme for large, tracking dishes at much greater expense, obsolete. Now we are revisiting the tracking ground station idea and swarms of LEO satellites with much cheaper automated versions possible.

Freddie from Brevard County, FL. I need another Explained on this one. When I was young, my father spoke of this theory that over long periods of time each planet in our solar system moves closer and closer to the sun. I understand how this can this can be discounted as planets are moving with a constant velocity(acceleration?), encountering no resistance, through the "vacuum" of space, allowing them to maintain their orbits.However, suppose an asteroid, comet, or meteor impacted the surface of a celestial body orbiting another with immense force, and possibly at a tangential angle opposite to its motion in orbit. Could this theoretically slow the orbiting body so much that it loses the velocity(/acceleration?) necessary to maintain its own orbit? If yes, then would it it be likely for the orbiting body to fall into the body its orbiting as our own satellites sometimes do? And if yes, why have I heard that the moon's orbit is slowly moving away from Earth's (about 1 1/2" a year) when the moon is (as we can plainly see) often bombarded these types of objects? Is this just a false fact that I was taught in elementary school? Please help me out.

One big error here. Geosynchronous orbits are not an integer number of orbits per one Earth rotation. They are the same period as Earth rotation just like geostationary, but they may be inclined relative to the equatorial plane and thus don't stay above the same exact location above the Earth. The form a figure 8 with height equal to the inclination when viewed from the ground. So, geostationary are special case of geosynchronous with zero inclination and thus appear to be at a stationary location relative to the ground.

You end up moving too slowly and fall back down to Earth. I mean, technically you can do it for a while if you keep using fuel, but if you want to just shoot it into orbit and have it stay there, it needs to move at a certain speed and that speed in low earth orbit is WAY too fast to be geosynchronous.

5:45 The higher your orbit is the longer your orbit it takes you to complete an orbit. Because your moving slower and slower, and the distances are getting bigger and bigger. All of this is true, except you actually need to accelerate faster and faster. However because the distance to complete an orbit around the Earth becomes much much greater as your altitude increases, the amount of distance transited over the Earth's surface over time is less and less.

@rob_i208 2 жыл бұрын

@@Dad_Brad That's not really how orbits work. You could launch something to geostationary orbital altitude and never accelerate it to orbit, but you wouldn't need to "boost" it towards Earth. It would just fall under gravity. However to answer your question it wouldn't be going any more or less faster than dropping it from virtually any other altitude. Gravity would accelerate to terminal velocity. Not possible for gravity to accelerate it beyond that.

Slowly decelerating again as it comes closer to the other end of the tunnel. If one person was standing in Peru, the other end of the tunnel would be in Vietnam. Earth Sandwich.

A geosynchronous orbit is that high Earth orbit allowing satellites to match Earth's rotation. Geostationary, which is located at 22,236 miles (35,786 kilometers) above Earth's equator, requires constant maintenance to keep the platform exactly above the earth location you choose.

The question, nobody asks for: If somehow the ground stops interacting with you, and you fall just through it, in which orbit would you end up? BEO (below earth orbit) ?

You'd orbit the earth. That orbit would be *inside* the Earth but it would still technically be an orbit.

If it was possible to create a tethered GEO station, everything in LEO and MEO would keep crashing into your tether. Good luck with that.

Ummm... NO! GEO and MEO are not just around the equator. They are at an angle. The ISS is such and almost everything else is as well.

@@rickkwitkoski1976 I think no matter where the GEO station was, there would be a lot of junk in the LEO and MEO layers below that would take it out.

yes, but they forgot about the overall weight of the elevator itself as only a very small fraction of the elevator structure is weightless.

How fast would you have to go in order for air resistance to feel solid when you hit it ? Just leaving this here for the random smart people.

So I never used my legs for rope climb. This isn't bragging. 😅 I lack the coordination. Same with swimming, which I'm pretty sure I'm not terribly fast at. You all should listen to Oscar Peterson's Garota de Ipanema. In my opinion, it's the best recording of the song, or at least the least muzak variant.

You must have a different body than mine. I can't climb ropes or swim even with legs.

@@toby9999 swimming was super hard for me to figure out, and I had a fear of drowning. I also get vertigo when I'm high up. Idk if that made a difference.
