Sedna may refer to:
Sétna or Sedna was the name of two legendary High Kings of Ireland:
90377 Sedna is a large minor planet in the outer reaches of the Solar System that was, as of 2015, at a distance of about 86 astronomical units (AU) from the Sun, about three times as far as Neptune. Spectroscopy has revealed that Sedna's surface composition is similar to that of some other trans-Neptunian objects, being largely a mixture of water, methane, and nitrogen ices with tholins. Its surface is one of the reddest among Solar System objects. It is most likely a dwarf planet.
For most of its orbit, it is even farther from the Sun than at present, with its aphelion estimated at 937 AU (31 times Neptune's distance), making it one of the most distant known objects in the Solar System other than long-period comets.
Sedna has an exceptionally long and elongated orbit, taking approximately 11,400 years to complete and a distant point of closest approach to the Sun at 76 AU. These facts have led to much speculation about its origin. The Minor Planet Center currently places Sedna in the scattered disc, a group of objects sent into highly elongated orbits by the gravitational influence of Neptune. However, this classification has been contested, because Sedna never comes close enough to Neptune to have been scattered by it, leading some astronomers to conclude that it is in fact the first known member of the inner Oort cloud. Others speculate that it might have been tugged into its current orbit by a passing star, perhaps one within the Sun's birth cluster (an open cluster), or even that it was captured from another star system. Another hypothesis suggests that its orbit may be evidence for a large planet beyond the orbit of Neptune.
From the corner of your eye, I may say I am with you.
Above the heads that look upward in disbelief.
I connect, disconnect, emote, reappear.
I don’t need to be known by the Universe.
I travel moment by moment - a star to every sky,
And We may answer any question put -
Like a vessel to the field of Knowledge
I was there and there
And now over here.
I was here and here
And now over there.
The fluttering of a thousand wings... The trampling of
a thousand hoofbeats...
The turning of a thousand heads... The silky silence of
flowing water...
Seamen may have heard until they turned their heads to
look...
To see into the vast open endless answer.
I am with you.
I am with you.
What is it and why is it that this is what we all
desperately need:
Home. A place to rest, lay down our head.
Not knowing why but promised some reward - in the end.
A strange Maternal process.
The spell is neither Word nor Deed alone, it merely is.
A strange Maternal process.
Tears hot on my cheeks know no limits of feeling or
time,
The sirens gone and the rivers dried up.
The invention of gunpowder compressed -
Spark!
The silent feline not acknowledging the mirror.
A Fever -
Love.
Brightest when misunderstood.
The answer to a question felt but unheard.
Mother is the most important word.
Mother is the most important word.
Mother is the most important word.
