Question: When did Tycho Brache come onto the planet earth?

Candidate passages:
There is a chapter entitled "Tycho" in Jules Verne's Around the Moon (Autour de la Lune, 1870) which describes the crater and its ray system.
Tycho was the location of the Tycho Magnetic Anomaly (TMA-1), and subsequent excavation of an alien monolith, in , the seminal science-fiction film by Stanley Kubrick and book by Arthur C. Clarke.
It also serves as the location of "Tycho City" in ""; a lunar metropolis by the 24th century.
In the film "Can't Buy Me Love", Cindy notices Tycho while looking through a telescope on her final "contractual" date with Ronny in the Airplane Graveyard.
In Robert A. Heinlein's book "The Moon Is a Harsh Mistress", Tycho is the location of the lunar habitat "Tycho Under".
In Jack Williamson's novel "Terraforming Earth", the crater is utilized for "Tycho Base", a self-sustaining, robot controlled installation aimed at restoring life to the (dead) planet Earth after an asteroid sterilizes the biosphere.
Tycho Station is a prominent location in The Expanse series of novels by James S.A. Corey.
In Heinlein's short story "Blowups Happen", a character hypothesizes that Tycho may have been the location of a sentient race's main atomic power plant, in a past time when the Moon was still habitable—and that the plant exploded, causing the craters, the rays spreading from Tycho, and the death of all life on the Moon.
Clifford Simak set a novelette "The Trouble with Tycho", at the lunar crater.
He also postulated that the crater's rays were composed of volcanic glass (tektites) akin to a theory postulated by NASA researchers Dean Chapman and John O'Keefe in the 1970s.
Crater Tycho figures prominently in the Matthew Looney and Maria Looney series of children's books set on the Moon, authored by Jerome Beatty.
In Roger Macbride Allen's "Hunted Earth" series of novels, the Naked Purples own a former penal colony in or around Tycho crater known as "Tycho Purple Penal" (see The Ring of Charon).

In the Ptolemaic system, each planet is moved by a system of two or more spheres: one called its deferent, the others, its epicycles.
The deferent is a circle whose center point exists halfway between the equant and the earth, marked by the X in the picture to the right where the equant is the solid point opposite the earth.
Another sphere, the epicycle, is embedded inside the deferent and is represented by the smaller dotted line to the right.
A given planet then moves along the epicycle at the same time the epicycle moves along the path marked by the deferent.
These combined movements cause the given planet to move closer to and further away from the Earth at different points in its orbit, and caused observers to believe that the planet even slowed down, stopped, and moved backward (in retrograde motion).
This apparent retrograde motion was one of the largest inconsistencies in Greek cosmological systems, and was one of Ptolemy's main reasons for creating the deferent, epicycle model.
The model with epicycles is in fact a very good model of an elliptical orbit with low eccentricity, where the main feature is an offset focus.
The well known ellipse shape does not appear to a noticeable extent when the eccentricity is less than 5%, but the offset distance of the 'center' (in fact the focus occupied by the sun) is very noticeable even with low eccentricities as possessed by the planets.
The geocentric model was eventually replaced by the heliocentric model.
However, the earliest heliocentric model, Copernican heliocentrism kept the deferents and epicycles because that made reasonably accurate predictions which agreed with observations more accurately than previous systems.
The epicycles of Venus and Mercury are always centered on a line between Earth and the Sun (Mercury being closer to Earth), which explained why they were always near it in the sky.
The elliptical model of Kepler eventually replaced epicycles only when observational methods (that Tycho Brahe and others developed) became sufficiently accurate to raise doubts about the epicycle model.
The Ptolemaic order of spheres from Earth outward is: Moon Mercury Venus Sun Mars Jupiter Saturn Fixed Stars "Primum Mobile" (First Moved).
Ptolemy did not invent or work out this order, which aligns with the ancient Seven Heavens religious cosmology common to the major Eurasian religious traditions.
The deferent-and-epicycle model had been used by Greek astronomers for centuries, as had the idea of the eccentric (a deferent which is slightly off-center from the Earth).
In the illustration, the center of the deferent is not the Earth but X, making it eccentric (from the Greek ἐκ "ec-" meaning "from," and κέντρον "centrum" meaning "center").
Unfortunately, the system that was available in Ptolemy's time did not quite match observations, even though it was considerably improved over Aristotle's system.
Sometimes the size of a planet's retrograde loop (most notably that of Mars) would be smaller, and sometimes larger.
This mismatch prompted Ptolemy to come up with the idea of an equant.
The equant was a point near the center of a planet's orbit which, if you were to stand there and watch, the center of the planet's epicycle would always appear to move at the same speed.
Therefore, the planet actually moved at different speeds when the epicycle was at different points on its deferent.
By using an equant, Ptolemy claimed to keep motion which was uniform and circular, although it departed from the Platonic ideal of uniform circular motion.
The resultant system, which eventually came to be widely accepted in the west, seems unwieldy to modern astronomers; each planet required an epicycle revolving on a deferent, offset by an equant which was different for each planet.
But it predicted various celestial motions, including the beginnings and ends of retrograde motion, fairly well at the time it was developed. 
In the context of the strip, Jesus Christ is a big fan of FPS and fighting games.
He enjoys shooting people in online games when they are talking, and "throwing up the horns" when he wins (this also makes him "fucking metal").
Also known for his legendary skill in "" - for his ability to "bring those blue sparks".
He has visited Tycho and Gabe for years and is on a personal level with them, such that he has gone Christmas shopping with Gabe for Tycho (while he did know what Tycho wanted for Christmas, he was unable to buy "the one unholy "object" his dark soul thirsts for", as it would damn even him.
They decided to settle for a Hickory Farms gift box).
Jesus also once warned Judas about "being a dick" for team killing.
In the strip, the character has also momentarily returned to Earth - not for the rapture, but out of excitement over the prospect of deep fried Twinkies. 
Marcel Brache (born ) is an American-born South African rugby union player.
He generally plays as a centre but can also play wing.
He represented Western Province from 2011 to 2013 in the Currie Cup and Vodacom Cup.
Brache represented the Stormers in Super Rugby during the 2012 season where he made 1 substitute appearance, but did not make the Stormers squad for the 2013 season.
Brache previously played for the Ikey Tigers in the Varsity Cup.
Brache joined Australian Super Rugby side the Western Force in late 2013 on a two-year deal before the 2014 Super Rugby season.
Brache is eligible to play for the U.S. national team, as he was born in Los Angeles.
