Is it possible to accurately measure how fast we are moving at any one time?
the earth spins the earth orbits the sun is the sun moving? the galaxy spins and moves? and on and on.
do we require reference points to calculate movement? — Preceding unsigned comment added by 79.65.5.120 ( talk) 13:29, 20 July 2019 (UTC)
FWIW - Excellent Question - Answer: "Nearly Two Million Miles Per Hour" => I've tried to answer (or, respond to) this question several times over the years - some of my efforts were published ( FaceBook and The New York Times) - and are copied below if interested - hope this helps in some way - in any case - Enjoy! :) Drbogdan ( talk) 22:09, 20 July 2019 (UTC)

How Fast Are We Moving Through Space? => "Nearly Two Million Miles Per Hour" [NOTE: Perhaps "Nearly One Million Miles Per Hour" may be better - see comments above]
(ie, 1.892 x 106 mph = 0.066 x 106/orbit sun + 0.043 x 106/sun + 0.483 x 106/orbit galaxy + 1.300 x 106/galaxy )

November 12, 2014Thank you for an Excellent article - Yes - a spacecraft landing on an astronomical object, Comet 67P, going 84,000 miles an hour ( /info/en/?search=Comet_67P ), is quite an accomplishment - however - for perspective - seems that airplanes routinely land on an astronomical object, spaceship planet Earth, going much, much faster - nearly 2 million miles an hour according to astronomers => https://web.archive.org/web/20181226060625/http://www.astrosociety.org/edu/publications/tnl/71/howfast.html - in any case - Thanks again for the Excellent article - and - Enjoy! :)

Speed is not an absolute measure. Planet Earth has a relative speed of 0 for airplanes (referring to its original position, the runway).
84,000 miles an hour is the relative speed of Comet_67P refering to Rosetta's original position.
Three big diferences:
- the acceleration process (which lasts 10 years)
- the distance (rendezvousing with the comet required travelling a cumulative distance of over 6.4 billion kilometres.)
- The automation (It will take the radio signals from the transmitter on Rosetta 28 minutes and 20 seconds to reach Earth, and the same to return to rosetta)2 Recommend
Dr. Dennis and Joanne Bogdan commented Pittsburgh, PA November 14, 2014
Yes - I *Entirely* Agree - Thank You *Very Much* For Clarifying - Landing On The Comet Is A Truly Great Technical Accomplishment Of Course - Enjoy! :)
Hello. I came across this term while modifiying Morphosis (disambiguation), and found that the article's lead sentence is unintelligible due to false syntax. However, I couldn't figure out how to appropriately fix it – without having the cited sources at hand. Can anybody perhaps help out? Regards-- Hildeoc ( talk) 19:56, 20 July 2019 (UTC)
