Nemesis - Nibiru - Wormwood. ?

Nemesis is a hypothetical hard-to-see red dwarf star or brown dwarf, orbiting the Sun at a distance of about 50,000 to 100,000 AU (about 0.8-1.5 light-years), somewhat beyond the Oort cloud.[1] This star was originally postulated to exist as part of a hypothesis to explain a perceived cycle of mass extinctions in the geological record, which seem to occur once every 27 million years or so. In addition, observations by astronomers of the sharp edges of Oort clouds, similar to that of the Solar System, around various binary (double) star systems, in contrast to the diffuse edges of the Oort clouds around single-star systems, has prompted some scientists to postulate that a dwarf star may be co-orbiting the Sun. Counter-theories also exist that other forces (like the angular effect of the galactic gravity plane) may be the cause of the sharp-edged Oort cloud pattern around the Sun. To date the issue remains unsettled in the scientific community.

Claimed periodicity of mass extinctionsIn 1984, paleontologists David Raup and Jack Sepkoski published a paper claiming that they had identified a statistical periodicity in extinction rates over the last 250 million years using various forms of time series analysis. They focused on the extinction intensity of fossil families of marine vertebrates, invertebrates, and protozoans, identifying 12 extinction events over the time period in question. The average time interval between extinction events was determined as 26 million years. At the time, two of the identified extinction events (Cretaceous-Tertiary and Late Eocene) could be shown to coincide with large impact events. Although Raup and Sepkoski could not identify the cause of their supposed periodicity, they suggested that there might be a non-terrestrial connection. The challenge to propose a mechanism was quickly addressed by several teams of astronomers.
Development of the Nemesis hypothesesTwo teams of astronomers, Whitmire and Jackson, and Davis, Hut, and Muller, independently published similar hypotheses to explain Raup and Sepkoski's extinction periodicity in the same issue of the journal Nature. This hypothesis proposes that the Sun may have an as yet undetected companion star in a highly elliptical orbit that periodically disturbs comets in the Oort cloud, causing a large increase in the number of comets visiting the inner solar system with a consequential increase in impact events on Earth. This became known as the Nemesis (or, more colorfully, Death Star) hypothesis.

If it does exist, the exact nature of Nemesis is uncertain. Richard A. Muller suggests that the most likely object is a red dwarf with magnitude between 7 and 12, while Daniel P. Whitmire and Albert A. Jackson argue for a brown dwarf. If a red dwarf, it would undoubtedly already exist in star catalogs, but its true nature would only be detectable by measuring its parallax; due to orbiting the Sun it would have a very low proper motion and would escape detection by proper motion surveys that have found stars like the 9th magnitude Barnard's star.

The last major extinction event was about 5 million years ago, so Muller posits that Nemesis is likely 1.0 to 1.5 light-years (63,000--95,000 AU) away at present, and even has ideas of what area of the sky it might be in (supported by Yarris, 1987), near Hydra, based on a hypothetical orbit derived from original apogees of a number of atypical long-period comets that describe an orbital arc meeting the specifications of Muller's hypothesis.

[edit] Other possible evidence: questions about orbital path of SednaThe extremely distant planetoid Sedna has an extra-long and unusual elliptical orbit around the Sun, well beyond Pluto,[6] ranging between 76 and 975 AU. Sedna's orbit is estimated to last between 10.5 and 12 thousand years. Its discoverer, Mike Brown of Caltech, noted in a Discover magazine article that Sedna's location doesn't make sense:

"Sedna shouldn't be there," said Brown. "There's no way to put Sedna where it is. It never comes close enough to be affected by the Sun, but it never goes far enough away from the Sun to be affected by other stars."

Brown postulates that perhaps a massive unseen object is responsible for Sedna's mystifying orbit, its gravitational influence keeping Sedna fixed in that far-distant portion of space.

Woodworm? Perhaps you mean Wormwood...

[AR15Truther2]

@Phoenix12212012 Thanks

[AzumiRM]

asteroids dont explode when they hit planets. they dont contain explosives and neither does earth.

[AR15Truther2]

@AzumiRM tunguska explosion

[Leadstorm76]

I believe it what comes around goes around haven't you seen the string of astroids that hit jupitor or saturn dont think that wont happen here.

[supergsx]

This guy is just making shit up. In astronomy and astrophysics, you don't invent something and then find it. You find it and then invent it.

@Hazy804 No like Gary Coleman

@Phoenix12212012 Its called Tyche Google it! & surprisingly its even on the Wikipedia website read about it

[YoyoYo91100]

wew i feel sad for dinos D:

[NyghtshroudeTV]

imagine if one could harness this planet and its power. Think of how easily you could rule this solar system.

Remember I was here.Thai

@AR15Truther2 there was no explosion at Tunguska. Just flattend trees from the passing rock's wake. Land was moved slightly outward from the impact zone, of course to fit something extra into the surface of the earth, some earth will have to give way to do so. No explosion though.
