The Dark Star Theory

On 7th October 1999 a small news item appeared in the inside pages of
various newspapers and Internet news servers that did little more than
raise a few eyebrows. An extract from MSN News stated:
"Two teams of researchers have proposed the existence of an unseen planet
or a failed star circling the Sun at a distance of more than 2 trillion
miles, far beyond the orbits of the nine known planets. The theory,
which seeks to explain patterns in comets’ paths, has been put forward in
research accepted for publication in two separate journals."

I believe this is the precursor to something quite extraordinary, the
implications of which are unknown to the many astronomers hoping to be
the first to discover this planet or failed star. The basis for my
belief lies far back in history, from myths and data recorded by our very
earliest civilisations. This proposed synthesis of myth and modern
science lead us in a remarkable direction.

1: it won't be a "Red Dwarf", because there is no evidence whatsoever
that there is one, instruments are no sensitive to image it, and it's
just not there.

2: It won't be a "Brown Dwarf" either for the following reasons:


"We are familiar with stars, which are luminous balls of gas that fuse
elements in their core. Stars are massive enough that the pressure and
temperature in their cores are enough to maintain fusion. Planets are
smaller, cooler objects which are, in general, not self-luminous. Planets
are bright because they reflect sunlight. Their mass is too small to have
fusion in the core.
A brown dwarf is an object that is somewhere in the netherworld between
stars and planets. By definition, a brown dwarf is an object that has a
mass less than is needed to sustain fusion, and at the lower mass end
they blend into planets."

read the entire text.

From my reading, it looks like brown dwarfs mass from about 10 Jupiter
masses to about 75 Jupiter masses. IMHO, that doesn't begin to square
with the projected mass of any Planet X theory; at least any that is based
on the 'work' of Sitchen and such-like.

Exactly, and it goes treble for "Red Dwarfs"



And Nancy's fantasy of a 20 *Earth*-mass brown dwarf PX is just silly. Or
did everyone already get the memo?





3: There is no "Planet X", no evidence to even suggest that such an
object exists.



End of story. Move along.
