Question: Do the statements in the Book of Abraham regarding Kolob's revolution time make any sense?
Criticism
"LDS doctrine regarding astronomy is permeated with references to time being measured, or 'reckoned' according to a star's or planet's rate of rotation. Furthermore, this 'reckoning of time' is a prime distinguisher in terms of 'greatness.' From the standpoint of modern cosmology, this makes no sense at all. Rates of rotation are largely arbitrary, and of little comment or concern from a fundamental point of view."

Response
Mr. Anderson and the authors of the web page have confused rotation with revolution. Though the technical distinction is often blurred, even by astronomers in today's world, at the time of Joseph Smith, the two terms denoted technically different things. 'To rotate' means to spin on an axis, like a top or like a planet. It applies only to an extended body. 'To revolve' means to go around. This term may be applied to a point that moves around another point. The Earth rotates on its axis once per day and a point on the surface of the earth revolves about the axis at the same rate. The Moon revolves about the Earth once per month. It also rotates about its axis at the same rate. This is not a coincidence, but the result of tidal dissipation. The Book of Abraham uses the term 'revolution' and it clearly gets the term right. According to Abraham 3:5,9,
- 5 And the Lord said unto me: The planet which is the lesser light, lesser than that which is to rule the day, even the night, is above or greater than that upon which thou standest in point of reckoning, for it moveth in order more slow; this is in order because it standeth above the earth upon which thou standest, therefore the reckoning of its time is not so many as to its number of days, and of months, and of years.
- 9 And thus there shall be the reckoning of the time of one planet above another, until thou come nigh unto Kolob, which Kolob is after the reckoning of the Lord’s time; which Kolob is set nigh unto the throne of God, to govern all those planets which belong to the same order as that upon which thou standest.
So the picture is geocentric (nothing wrong with that — Relativity tells us that one point is as good as another), and clearly refers to the revolution of the heavenly bodies about the Earth. The Earth's reckoning has the shortest period — one revolution per day for a point on the surface. The Moon is next, with an orbital period of 27.32 days. The Sun is slower still, with a sidereal period of 365.256363004 days. And, apparently, Kolob revolves about the Earth once per... Well, does Abraham ever give the time for Kolob to revolve around the Earth, as seen from Earth? He never says that God lives on Kolob, but only that Kolob is one of the great stars and is nearest to the throne of God. Then, in Abraham 3꞉4, we read
- 4 And the Lord said unto me, by the Urim and Thummim, that Kolob was after the manner of the Lord, according to its times and seasons in the revolutions thereof; that one revolution was a day unto the Lord, after his manner of reckoning, it being one thousand years according to the time appointed unto that whereon thou standest. This is the reckoning of the Lord’s time, according to the reckoning of Kolob.
which seems to say that Kolob's orbital period about the throne of God is 1000 years, and that it is used by God as the definition of the Lord's day. Of course, since Kolob is still far above the Sun, as seen from the Earth, is "moveth in order more slow" (Abraham 3꞉4), so it encircles and "governs" all intervening stars and planets. So is the Throne of God at the center of the Galaxy (in which case it would take 22,000,000 years to orbit the Earth) or at the center of the Universe (in which case we have no idea if it is revolving at all. — If it is, observations limit the rotation of the Universe to be a very small number).
Conclusion
So there
