NOTES: Solar System Debris
Comets: Nucleus is a dirty snowball (Whipple) from 1-10 km.
We see ion tail, a veil of evaporated ions swept back by solar
wind. It always points away from the sun, and has a magnetic
field creating a glow like the aurora borealis. A dust tail, visible
mainly in the infrared, is left in its wake. Comets break up a
bit each time they come close to the sun. Debris in earth's
orbit creates a meteor shower at a regular time each year.
(Like the Leonids--from constellation Leo in mid-November.)
The radiation, solar wind sublimate jets, making nucleus spin.
Most comets spend most of their time in the Oort Cloud far
beyond Pluto. (Few in the Kuiper Belt just beyond Pluto.)
Asteroids: space rocks. The asteroid belt: over 100,000
between Mars and Jupiter. Ceres--largest 1000 km diam.,
Pallas, Vesta, Juno. Either it is a broken up planet or Jupiter's
gravity kept it in pieces. Kirkwood gaps--fraction of Jupiter’s period.
The Trojans: 700 carried around in gravity wells in front of
and behind Jupiter in its orbit (at Lagrangian Points).
The Amors--5 large ones that come near earth's orbit.
The Apollos--5 large ones that cross earth's orbit.
Many others in Kuiper Belt, Oort cloud, and dispersed.
Meteors--shooting stars, rocks burning up as they fall in atmos.
Meteoroid--rock in space, Meteorite--rock on earth from space,
stony to stony-irons. Carbonaceous chondrites-stars. 11 m/s
Dwarf Planets? Eris is 1 ½ Pluto’s size,
Sedna is about 4/5ths Pluto’s size.
It’s orbit varies from 3 to 10 times Pluto’s distance.
There is speculation that there might be a very large planet
(brown dwarf) at a great distance
Two reasons:
1. Sumerian lore—the Planet Nibiru
2. A disturbance in the orbit and spin of Uranus and Neptune.
The Naval
Observatory
called it Planet X
Nemesis is
Physicist’s Luis
Alvarez’ (asteroid
extinction of
dinosaurs) name for
his theory for
explaining periodic
extinctions every
25 million years.
Zechariah Sitchin says Nibiru has
A period of 3600 years and beings
from it brought human genetics.
Sumerian writings and drawings
suggest a ‘Twelfth Planet’.
Comet Halley appearances:
William, the Conqueror invades England--1066
Giotto—the Magi 1304-1306 Comet Halley
A comet in the sky was blamed for the
eruption of Mount Vesuvius in 1631
Mark
Twain—1835-1910
‘I came in with Halley's Comet in 1835.
It is coming again next year (1910),
and I expect to go out with it. ‘
Sacrifice of Girl Stopped
Fanatics About to Offer Up Girl To Foil Comet When Posse
Arrives
Special to the Washington Post.
Aline, Okla. May 18 1910 – Miss Jane Warfield, 16 years old,
was today
rescued from a band of religious fanatics 25 miles southwest
of this place. She was about to be offered up as a sacrifice to
make a blood atonement that the sins of the world might be
forgiven.
Solar System Debris
Comets: Nucleus is a dirty snowball (Whipple) from 1-10 km.
Nucleus of comet Halley:
We see the ion tail, a veil of evaporated ions swept back by
solar wind. It always points away from the sun, and has a
magnetic field creating a glow like the aurora borealis. A dust
tail, visible mainly in the infrared, is left in its wake.
Comet Hale-Bopp—1997. Rare visible dust tail.
Comets break up a
bit each time they come close to the sun.
Cometary debris in earth's
orbit may create a meteor shower at a regular time each year.
(Like the Leonids--from constellation Leo in mid-November.)
The radiation, solar wind sublimates jets,
making comet nucleus spin
Most comets spend most of their time in the Oort Cloud far

Asteroids: space rocks. The asteroid belt:
over 100,000 between Mars and Jupiter.
Ceres--largest asteroid in Asteroid Belt--1000 km diam.,
The asteroid belt is either a broken up planet
(unlikely) or Jupiter's gravity kept it in pieces.
Kirkwood gaps --fraction of Jupiter’s period
The Trojans: 700 carried around in gravity wells in
front of and behind Jupiter in its orbit (at Lagrangian
Points).
The Amors--5 large ones that come near earth's orbit.
The Apollos--5 large ones that cross earth's orbit.
Meteors--shooting stars, rocks burning up as they fall

Meteoroid--rock in space, Meteorite--rock on earth
from space
Stony, irons, stony-irons
Carbonaceous chondrites: with carbon chondreules
Formed in supernova explosions
