2581/
A brown dwarf is a very small, dark object, with a mass less
than 1/10 that of the Sun. They are "failed stars"
– globules of gas that have shrunk under gravity, but
failed to ignite and shine as stars.
2582/ A bucket filled
with earth would weigh about 5 times more than the same bucket
filled with the substance of the Sun. However, the force of
gravity is so much greater on the Sun that a man weighing
150 pounds on our planet would weigh 2 tons on the Sun.
2583/ A car travelling
at a constant speed of 60 miles per hour would take longer
than 48 million years to reach the nearest star (other than
our Sun), Proxima Centauri. This is about 685,000 average
human lifetimes.
2584/ A cosmic year is
the amount of time it takes the sun to revolve around the
center of the Milky Way, about 225 million years.
2585/ A day on the planet
Mercury is twice as long as its year. Mercury rotates very
slowly but revolves around the Sun in slightly less than 88
days.
2586/ A dog was killed
by a meteor at Nakhla, Egypt, in 1911. The unlucky canine
is the only creature known to have been killed by a meteor.
2587/ A galaxy of typical
size – about 100 billion suns – produces less
energy than a single quasar.
2588/ A neutron star
is the strongest magnet in the universe. The magnetic field
of a neutron star is a million million times stronger than
Earth's magnetism.
2589/ A new star is born
in our galaxy is born every 18 days. About 20 new stars are
born each year. For comparison, there are 100,000 million
stars in our galaxy.
2590/ A pulsar is a small
star made up of neutrons so densely packed together that if
one the size of a silver dollar landed on Earth, it would
weigh approximately 100 million tons.
2591/ A space vehicle
must move at a rate of at least 7 miles per second to escape
Earth's gravitational pull. This is equivalent to going from
New York to Philadelphia in about 20 seconds
2592/ A sunbeam setting
out through space at the rate of 186,000 miles a second would
describe a gigantic circle and return to its origins after
about 200 billion years.
2593/ A teaspoon of neutron
star material weighs about 110 million tons.
2594/ A typical nova
explosion releases about as much energy as the Sun emits in
10,000 years, or as much as in 1,000,000,000,000,000,000,000
nuclear bombs.
2595/ The average garden
variety caterpillar has 248 muscles in its head.
2596/ The average human produces 10,000 gallons of saliva
in a lifetime.
2597/ The first words
spoken by Thomas Edison over the phonograph were: Mary had
a little lamb.
2598/ A baby in Florida
was named: Truewilllaughinglifebuckyboomermanifestdestiny.
His middle name is George James.
2599/ The Gulf Stream
could carry a message in a bottle at an average of 4 miles
per hour.
2600/ A cow's only sweat
glands are in its nose.
