Earth Is Moving Toward
The Same Meteor Swarm
That Scientists Believe
Caused The 1908
Tunguska Event.
Some scientists are convinced
the Tunguska explosion of 1908,
during the last week of June 1908,
which flattened 80 million trees
in Russia, was caused by an object
from the Taurid meteor swarm.
The last week of June 2019
will mark the point when
we are the closest to the
center of this meteor swarm,
so the risk will be the greatest.
CBS News said our planet
“... will approach
within 30,000,000 km
of the center
of the Taurid swarm”
by the end of this month …"
That will be the closest
we have been to the
center of the meteor swarm
since 1975, and
the next close encounter
will be in 2032.
So, if you are an astronomer,
"perfesional" or "amachure"
this is a great viewing opportunity,
assuming no meteor hits you.
The 30 million kilometers
is the distance measured
from the exact center
of the meteor swarm.
Some scientists believe
giant rocks from
this meteor swarm
have been responsible
for multiple past
“once-per-1,000-years
catastrophic events on Earth”
As Earth orbits the Sun,
its orbital path often goes through
dust and debris left by comets.
Matter no bigger than a grain of sand
busts into Earth’s atmosphere
and burns up as “shooting stars”.
The Taurid swam
is an exceptionally large
cloud of debris, probably
from Comet 2P/Encke,
Among the observational evidence
is increased “fireball”
shooting star activity
when Earth gets close
to the “Taurid Swarm”,
and increased impacts
on the Moon.
The June 30th, 1908
Tunguska event,
from Wikipedia:
"Early estimates of the energy
of the air burst range from
10–15 megatons of TNT
(42–63 petajoules)
to 30 megatons of TNT
(130 PJ),
depending on the exact height
of burst estimated when the
scaling-laws from the effects
of nuclear weapons are employed."
"However, modern supercomputer
calculations that include the effect
of the object’s momentum
find that more of the energy
was focused downward than
would be the case from
a nuclear explosion and estimate
that the airburst had
an energy range from
3 to 5 megatons of TNT
(13 to 21 PJ)."
"The 15-megaton (Mt) estimate
represents an energy
about 1,000 times greater
than that of the atomic bomb
dropped on Hiroshima, Japan
—roughly equal to that of the
United States’ Castle Bravo (15.2 Mt)
ground-based thermonuclear detonation
on 1 March 1954, and about one-third
that of the Soviet Union‘s Tsar Bomba
explosion on 30 October 1961
(which, at 50 Mt, is the largest
nuclear weapon ever detonated)."
"It is estimated that the Tunguska
explosion knocked down some
80 million trees over an area
of 2,150 km2 (830 sq mi),
and that the shock wave
from the blast would have
measured 5.0 on the Richter
magnitude scale."
A couple of years ago,
scientists discovered
a “new branch” of the
Taurid meteor swarm
that contains “asteroids
up to 1,000 feet wide”
… flying past us
every few years.
Previous encounters
with the Swarm
in 2005 and 2015 p
roduced showers
of bright meteors
observed all around
the world.
In 1975 the Swarm
contacted the Moon,
making the Apollo
seismic sensors ring
with evidence
of objects hitting
the lunar surface.
And now for
some good advice:
some good advice:
Wear your bicycle helmet
every minute, of every day,
during the last week
every minute, of every day,
during the last week
of June 2019 ( next week ).
I would be doing so,
but I don't own a bicycle helmet,
but I don't own a bicycle helmet,
so I will be living dangerously
next week -- but looking up at all times
when I'm outdoors, because in the early
1980's, I once side-stepped a punch,
so I plan to side step the meteor,
if I see one coming.
