Sun's Nemesis Pelted Earth with Comets, Study Suggests


www.space.com
A dark object may be lurking near our solar system, occasionally kicking comets in our direction.

Nicknamed "Nemesis" or "The Death Star," this undetected object could be a red or brown dwarf star, or an even darker presence several times the mass of Jupiter.

The Footprint of Nemesis

A recently-discovered dwarf planet, named Sedna, has an extra-long and usual elliptical orbit around the Sun. Sedna is one of the most distant objects yet observed, with an orbit ranging between 76 and 975 AU (where 1 AU is the distance between the Earth and the Sun). Sedna's orbit is estimated to l

Xena/Eris is a dwarf planet.

NEAT comet was a normal comet that happened to be very bright.

You people are so superstitious...

That wasn't an actual insult, it was a Firesign Theatre reference

It is just that I read about NASA finding it some years ago, wierd how we dont add them to our solar system count if they orbit our sun..

This is slightly off topic, but it is a cool find.

Dark Asteroids Found Near Earth

A new infrared telescope has found 16 to 20 previously unknown asteroids that come close to Earth.

The asteroids are dark, with most reflecting less than one-tenth of the sunlight that hits them. One object is as dark as asphalt, reflecting less than 5 percent of its light.

The objects, which some scientists suspect may be spent comets, pose no threat to the planet, though how they got here remains a mystery.

"This population tells us a lot about the solar system's history and formation," said NASA's Amy Mainzer, the lead researcher on a project to use a new infrared telescope called WISE to search for near-Earth objects.

The Wide-Field Infrared Explorer, or WISE, has been on the hunt for about seven weeks, mapping the sky for objects that radiate in the infrared. Within six months, WISE is expected to have surveyed the entire sky.

"We're just getting the first data on asteroids in general," Mainzer told Discovery News. "It's still really, really early so we don't have an idea of how big this population actually is."

About half of the newly found objects reflect less than 10 percent of the sunlight that hits them, making them difficult if not impossible to spot with visible light telescopes. WISE finds objects by their heat emissions.

The newly discovered objects have highly inclined orbits, which has planetary scientist Richard Binzel, with the Massachusetts Institute of Technology, thinking that they are comets which have had all their surface ices striped away by heating, leaving just a comet nuclei orbiting in the inner solar system.

Comets are believed to have formed in the frozen outer regions of the solar system, but occasionally some are bumped in closer to the sun due to the gravitational pull of the giant planet Jupiter. As they orbit closer to the sun, ices on their surface vaporize, forming a distinctive fuzzy tail around the comet's body. Binzel believes WISE is finding extinct comets.

"We're constantly finding new stuff," Mainzer said. "We're drinking from the fire hose of knowledge right now. What we've seen is a very exciting glimpse of what is to come."


Enjoy!

Thanks Aggie man. Also a great read.

These are exiting times we live in.

Our "solar system count" is the count of normal planets; it's down to 8 since the whole Pluto thing. In fact, Xena/Eris was the impetus for the pluto thing! Dwarf Planets are different from Planets in fairly arbitrary ways.

Bad thing is we are in/approching the end of one of those intervals - so we better wake the F-up and get our crap together before it happens again!


I'm awake.

Now, if there is anything I can do to prevent a catastrophic event, please enlighten me.
Not knowing would in a such a case be mine preferred choice.

According to computer simulations inspired by the finding of "hot" Jupiter-class planets found in inner orbits around nearby stars, the Solar System's own Jupiter may have formed 10 percent farther from the Sun than it is now, and then spiralled in by about 0.45 AUs (70 million kilometers or 44 million miles) over at least 100,000 years as it lost angular momentum to drag within the thick dust disk that surrounds young stars. Supporting evidence of this in-migration from an unusual group of 700 or so rocky bodies known as the Hilda asteroids, which orbit the Sun three times for every two made by Jupiter, and of which vast majority have slightly elongated elliptical orbits, whereas many other asteroids have near-circular orbits. Computer simulations (led by Fred Franklin’s team at the Harvard-Smithsonian Center for Astrophysics) indicate that Jupiter's early in-migration would have ejected any proto-Hilda asteroids with circular orbits from the Solar System and would have further elongated the orbits of those that remained (Franklin et al, 2004). Luckily, Sol's dust disk was probably thin compared with those stars that dragged their outer gas giants into inner orbits closer than Mercury or into the stars themselves, perturbing the orbits of any developing, inner terrestrial planets. Indeed, astronomer Phil Armitage speculates that the in-migration of Jupiter could also have disturbed the proto-planetary bodies of the inner Solar System so that they collided more frequently, to spur the formation and growth of Earth itself.

Ancient Sumerian texts indicate that the Earth (" Tiamat ") was struck by a large planet, which moved it into its present orbit, and created the Moon and the Asteroid Belt. In his books, The Twelfth Planet and The Cosmic Code, Zecharia Sitchin outlines this "celestial battle" as described in the Babylonian text called Enuma elish. The planet "Marduk" (the Sumerian " Nibiru "), as it came into the solar system on its clockwise elliptical course, struck Tiamat, which was moving in its ordained counterclockwise orbit. One of Marduk's satellites struck Tiamat first, followed by two more of Marduk's moons. Then Marduk itself, an enormous planetary body, struck Tiamat, smashing one half of the planet into pieces, which became the Earth's Moon and the "Great Band" (Asteroid Belt). The other half of the planet, which was struck by a smaller moon of Marduk, was moved into a new orbit, along with a chunk of material which became its moon. The new planet was then called "KI," meaning "cleaved one." The Earth's original moons were dispersed, many changing the direction of their orbits.

According to you? And don't say "Sumerians."

Sorry but this is all dependent upon translation and no one is going to translate something as what they think cannot be correct. The translation of this ancient language is not straightforward, as it is still not fully understood. We have no idea what they were talking about or their own words meant to them.

Jupiter has a slightly elliptical or oval shaped orbit...
...accroding to the THE ASSYRIAN DICTIONARY...Neberu is Jupiter
...Did you look at the vid...The Chicago Assyrian Dictionary, initiated in 1921 by James Henry Breasted, is compiling a comprehensive dictionary of the various dialects of Akkadian, the earliest known Semitic language that was recorded on cuneiform texts that date from c. 2400 B.C. to A.D. 100 which were recovered from archaeological excavations of ancient Near Eastern sites. The Assyrian Dictionary is in every sense a joint undertaking of resident and non-resident scholars from around the world who have contributed their time and labor over a period of seventy years to the collection of the source materials and to the publication of the Dictionary.... oi.uchicago.edu...
