►One light year the distance light travels in a year at the
speed of 186,000 miles per second is just under six thousand billion miles.
Earth's nearest neighbor in space, outside our own solar system is four light
years away (about 24 trillion miles).
►"Happy
Birthday" was the first song to be performed in outer space, sung by the
Apollo IX astronauts on March 8, 1969.
►Any
free-moving liquid in outer space will form itself into a sphere, because of
it's surface tension.
►In 1959, the
Soviet space probe "Luna Two" became the first manmade object to reach the
moon as it crashed onto the lunar surface.
►It was
discovered on a space mission that a frog can throw up. The frog throws up its
stomach first, so that the stomach is dangling out of it's mouth. Then the
frog uses its' forearms to dig out all of the stomach's contents and then
swallows the stomach back down again.
►Laika the
dog, was the first living thing which was sent to space
►The first
manned space flight happened on the 12th April 1961, when Yuri Gagarin made a
complete orbit of the Earth before landing safely back in Russia
►In 2001, the
Russian Mir space station was deliberately de-orbited, and broke apart during
atmospheric re-entry. Mir entered the Earth's atmosphere on March 23, 2001,
near Nadi, Fiji, and fell into the South Pacific Ocean. Previously, its two
predecessors, Salyut 6 and Salyut 7, were deorbited in a controlled manner as
well.
►Due to the
Earth's surface being primarily water, most objects that survive reentry land
in one of the world's oceans. The estimated chances that a person will get hit
and injured is around 1 in a trillion
►More than 100
metric tons of man-made objects reenter in an uncontrolled fashion each year.
Of satellites that reenter, approximately 10-40% of the mass of the object is
likely to reach the ground.[16] On average, about one catalogued object
reenters per day. Approximately a quarter of all objects are of U.S. origin.
►A day on the
planet Mercury is twice as long as its year
►If you are
having problems remembering the planets in their correct order, just remember
this sentence "My very educated mother just served us nine pickles," Mercury,
Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto.
►Our sun and
the surrounding planets orbit around the center of the Milky Way galaxy once
every 250 million years.
►Planet
Jupiter spins so fast that there are 2 sunrises and 2 sunsets every 24 hours
by earth time.
►Planet Venus
is the only planet to spin counter-clockwise
►Pluto has the
longest year, lasting 247 years and 256 days in Earth time (90,472 days
including 61 leap years).
►If the
sun stopped shining suddenly, it would take eight minutes for people on earth
to be aware of the fact.
►For 186 days
you can not see the sun in the North Pole.
►Every eleven
years the magnetic poles of the sun switch. This cycle is called "Solarmax"
►At the
distance at which our sun is located from the center of the Milky Way galaxy,
Earth and the rest of our solar system are moving at a speed of about 170
miles per second around the center.
►After the
sun, the closest star to Earth is 25,000,000,000,000 miles away.
