Is planet earth moving towards the Sun, helped by jets and sattelites taking off from earth?

Question

Greenwich atomic clock altered.?
Rockets used to manouvre Sattelites ?

Answer 1

have you had a bad dream???

Answer 2

Jet airplanes and satellites are still part of the Earth-Moon system, (as is the atmosphere that jet airplanes fly in). There can be no net change unless mass leaves the system.

The most efficient trajectory for interplanetary probes do slow the Earth down in its orbit. Most interplanetary probes would launch the same direction that the Earth is traveling (and rotating) to conserve fuel. Per conservation of momentum, the loss would break down like this:

M_e * V_ei + m_s * v_si = M_e*V_ef + m_s*v_sf

M_e is mass of Earth (about 6 x 10^24 kg)
V_ei is Earth's initial velocity (about 29.8 km/sec)
V_ef is Earth's final velocity after departure of the satellite

m_s is the satellite's initial mass
v_si is the satellite's initial velocity (about 30.25 km/sec once the Earth's rotation rate is added to the Earth's speed)
m_s is the satellite's final mass
v_sf is the satellite's final speed.

Earth's initial momentum is about 1.79 x 10^29 kg m/sec

If the satellite is about 1000 kg, it's initial momentum is about 30.25 x 10^6 kg m/sec

If the satellite speeds up to escape velocity (about 11.2 km/sec relative to Earth, or 29.8 km/sec + 11.2 km/sec = 41 km/sec), it's momentum will be 41 x 10^6 kg m/sec.

That's a net gain of 10.75 x 10^6 kg m/sec that must be subtracted from Earth's momentum. That's 1.79 x 10^29 - 10.75 x 10^6. Plug it into your calculator and see what you get (hee, hee, hee).

In other words, the Earth does lose some momentum and speed, which does result in the Earth's orbit becoming smaller and in the Earth being closer to the Sun, but you'll never be able to measure the difference unless you launch a 1000 kg interplanetary probe once per second for 29.5 billion years.

Answer 3

The answer is No! Man is not that clever. We may be the predominant species and the most intelligent animals on earth (that we know about) but it would take a lot more than our current jets or rockets to move this mass called Earth from its natural orbit

Answer 4

No, the only thing that keeps us close to the sun is the sun's gravitational pull towards us. I seriously doubt that jets and satellites would aid this process in any way. I'm not sure if our own gravitational pull towards the sun helps but I think it does. Other than that the only other thing that could help is if we lived in some fifth dimension, but that wouldn't work out too well, according to scientist we would just spiral into the sun. So, no...

Answer 5

No. If they all were launched pointing the same direction it could conceivably have an effect on the earth, although it would be a very small one. But they're all launched pointing in different directions, so all the effects cancel each other out.

Answer 6

I think aliens are hovering in space and blowing the earth towards the sun with their very powerful lungs.

Answer 7

no dear, planet earth doesnt depend in artificial power,
earth itself generate what we call gravity.
gravity and accelaration makes the compression and thus electromagnetism is present in the rotation we undergo. in the issues of north and south poles, thus we have the pull and earth rotates and revolve around the sun by itself...
the one you mentioned are comics of galaxy guide.
take care.

Answer 8

No - The rockets taking off when the sun is out counteracts those taking off at night - that's why they have some at night and some in the day time.. LOL !

Answer 9

No!
For size comparison.....
Would throwing a pea at a car help to move it?

Answer 10

I don't think so....but it might be moving towards the sea.

Answer 11

possibly the stupidest question I've read. No by the way.
