Hello again, Crythias,
Here's what I got (approximate speeds -- pardon the mixing of miles and kms):
2 miles/s -- fastest jet
8 miles/sec -- apollo 10
20 km/s and up -- coronal mass ejections
40 miles/sec -- interplanetary spacecraft
80 miles/sec -- solar tornados
150 miles/sec -- speed the Milky Way moves towards Andromeda
1,200 km/s -- nebula jets
2,000 km/s -- velocity of spiral nebulae
4,000 km/s -- expansion velocity of the cosmological "local group"
15,000 miles/s -- nebulae moving away from earth
123,800 km/s -- speed of light through diamond
90,000 miles/s -- speed of lightning
100,000 miles/s -- speed of signal through telephone wires
Santa's Sleigh -- 8.3 million mph!
Key sources are listed below. Let me know if you need any additional
information. This was fun!
Kinematics of 1200 Kilometer per Second Jets in He 3-1475
Spectroscopic observations of a protoplanetary nebula He 3-1475 with
the Space Telescope Imaging Spectrograph reveal the kinematics of its
high-velocity (1200 km s-1) jets.
The Convergence Depth of the Local Universe
The Local group and its neighbors all appear to be moving with respect
to the cosmic microwave background radiation (CMB); searching for the
convergence length of this flow has been a critical problem in
cosmology. Giovanelli and collaborators argue that the flow decreases
steadily as larger volumes of the universe are sampled, finding that
it ends or "converges" at distances corresponding to an expansion
velocity of only 4000 km/s or so.
THE DISCOVERY OF COSMIC EXPANSION
1910-1920: Slipher measures Doppler shifts of bright spiral nebulae.
He finds that they are moving fast, up to ~ 2000 km/s, nearly all away
from the Milky Way
Speed of light through various media:
HIPASS Bright Galaxy Catalog
Velocities are color coded in bins of 1000 km/s:
dark blue circle v < 1000 km/s
light blue cross 1000 < v < 2000 km/s
green star 2000 < v < 3000 km/s
yellow triangle 3000 < v < 4000 km/s
orange square 4000 < v < 5000 km/s
red plus 5000 < v < 6000 km/s
red cross v > 6000 km/s
BALL OF LIGHT CLOCKED AT 1,800 MILES/SECOND!
These researchers were monitoring the top of a thunderstorm with
low-light, high-speed video equipment, when the ball of light "popped
out" of the top of a thundercloud and flashed across their
instrument's field of view in 1/10 of a second.
Santa From a Physicist's Perspective.
Santa's sleigh MUST move at about 8.3 MILLION MPH or 2,300 miles per
SECOND ? 3000 times the speed of sound
CORONAL MASS EJECTIONS
Coronal Mass Ejections (CMEs) are clouds of electrified, magnetic gas
weighing billions of tons ejected from the Sun and hurled into space
with speeds ranging from 12 to 1,250 miles per second (about 20 to
2,000 kilometers per second).
The earth orbits around the sun at a speed of about 18.51 miles per second
Lightning travels 90,000 miles per second
Telephone signals travels at 100,000 miles per second
5,000 mph jet ready for test flight
Once the spacecraft gets to Mars, it has to slow down from its 5.9
km/s (13,200 mph) speed relative to Mars to its desired 29 hour orbit
capture velocity of 4.7 km/s (10,510 mph) or less.

Vast solar tornadoes, which can wreak havoc upon electric systems,
satellites, and computers, have been discovered by the European Space
Agency's SOHO spacecraft....SOHO has detected a dozen tornadoes, some
nearly as wide as the Earth and gusting up to 300,000 mph
Space Ship Earth?A Cosmic Gran Prix
...So the speed at which we rotate on our axis at the equator is a
little over 1,000 mph.
...the speed that we travel around the Sun is 66,660 mph.
...solar system speed is roughly 43,200 mph.
...Our galaxy is also spinning around it?s own central mass (or black hole). The
speed of this galactic rotation is an incredible 489,600 mph
...The speed of our galaxy towards Andromeda is 180,000 mph,
...our ?local? group of galaxies, which consist of about 30+ such galaxies,
are being drawn towards a ?galaxy supercluster? in Virgo at 540,000 mph!!
Mount Wilson Observatory at Pasadena, Calif., reports the discovery in
two nebulae of apparent movement away from Earth at the rate of 15,000
miles per second

"1000..100000 miles per second"
"10000..1000000 miles per hour"
and so on with km/s
