Template:Quote Sagittarius A*, officially abbreviated as Sgr A* and colloquially as SagA*, is the system in the Galactic Centre region that is recognized as the exact centre of the Milky Way galaxy. It is 25,899.99 light-years away from Sol. The system is home to the only known Supermassive Black Hole in the galaxy, as well as a white B-type star called Source 2. Dedicated explorers are traditionally expected to visit Sagittarius A* at least once in their careers due to its significance, but any pilot can make the trip provided they prepare their ship with long-range travel in mind.

Only 3.66 ly away from Sagittarius A* is the system Stuemeae FG-Y d7561, where Explorer's Anchorage is located. Explorer's Anchorage is the closest Starport to both Sagittarius A* and Beagle Point, as well as the most distant Starport from Sol. It is a convenient rest stop for Sagittarius A* visitors and other travelers passing through the Galactic Centre.

History

Sagittarius A* was documented by Universal Cartographics at some point, but remained uncharted and unexplored until December 1, 3300, when CMDR Zulu Romeo, piloting the Cobra Mk III Useless Reptile, became the first human to enter and scan the system while scouting a route for the First Great Expedition. A wave of visitors followed beginning on January 8, 3301 with CMDR Erimus Kamzel, and in short order Sagittarius A* became a significant touchstone for explorers and independent expeditions. Its importance was commemorated on October 25, 3302 with the addition of Tourist Beacon 0082 "The Centre", which remains the only permanent artificial structure in the system.

During the Distant Worlds II expedition of 3305, the expedition members constructed Explorer's Anchorage, an Orbis starport, in the nearby Stuemeae FG-Y d7561 system to serve as a research centre and rest stop for visitors to Sagittarius A*.

Notes

It is important to note the distinction between Sagittarius A and Sagittarius A*. The former is a complex radio source, while the latter is the supermassive black hole that is part of that source.
On February 18, 2016, Sagittarius A* became the first location where the theoretical instance cap for Elite Dangerous was broken, with over 50 player ships recorded in the same instance. Soon after, this record was broken with 101 players recorded.
The maximum surface scan range for Sagittarius A* is 144,278 Ls.^[1]^[2]

-==A Guide to Getting There==
+==History==
-Sagittarius A* is 25,900 light years from Sol. It will take roughly 700 jumps to reach the system with a 35-40 ly jump range, which means around 10 hours of travel time without any stops along the way; many pilots prefer to split the voyage into multiple segments over a period of several days or weeks. The fastest time in which Sagittarius A* can be reached is approximately 2 hours, provided an [[Anaconda]] with an 80 ly jump range is used with [[Neutron Highway|neutron star supercharging]].
+Sagittarius A* was documented by [[Universal Cartographics]] at some point, but remained uncharted and unexplored until December 1, 3300, when CMDR Zulu Romeo, piloting the [[Cobra MkIII|Cobra Mk III]] ''Useless Reptile'', became the first human to enter and scan the system while scouting a route for the First Great Expedition. A wave of visitors followed beginning on January 8, 3301 with CMDR Erimus Kamzel, and in short order Sagittarius A* became a significant touchstone for explorers and independent expeditions. Its importance was commemorated on October 25, 3302 with the addition of [[Tourist Beacon]] 0082 "The Centre", which remains the only permanent artificial structure in the system.
-A voyage to Sagittarius A* and back is not easy - in fact, it is sometimes said to be quite dangerous, but if you ping every system with your [[Discovery Scanner]] and explore the ones that look valuable, it can be extremely profitable - you can make several tens of millions from a Sagittarius A* trip.
+During the [[Distant Worlds II]] expedition of 3305, the expedition members constructed [[Explorer's Anchorage]], an [[Orbis]] [[starport]], in the nearby [[Stuemeae FG-Y d7561]] system to serve as a research centre and rest stop for visitors to Sagittarius A*.
-===The Right Stuff===
-If you want to set off on the journey, you need to be equipped properly''':'''
-*'''An exploration ship''' - you can't go exploring without having a ship meant for it! [[Diamondback Explorer]]s are particularly recommended for exploration due to their low cost (2 million credits) and very high maximum jump range (34ly). [[Asp Explorer]]s have a higher jump range at 37ly, but they are much more expensive at a price of 6 million credits. [[Anaconda]]s are capable of reaching up to 40ly, but it is extremely expensive. Shorter voyages to other locations like the Orion Nebula can be accomplished in a [[Cobra MkIII]] or a [[Hauler]], however.
-*'''[[Detailed Surface Scanner]]''' - Detailed surface scans will allow mapping surfaces with probes, revealing any significant points of interest on the planet's surface, as well as awarding a credit bonus if the probe efficiency target has been met.
-*'''Class D modules''', except [[Frame Shift Drive]] (FSD) - Having Class D modules will increase your jump range, but your FSD and fuel scoop should be the best you can afford. The best FSDs cost between 160 thousand upwards beyond 50 million depending on size. Don't worry that using D-class modules will hinder your ship's performance, class D modules are sufficient for exploration (except for the fuel scoop and FSD), including [[Life Support]], [[Power Plant]], and [[Thrusters]]. Installing an A-rated smaller Power Plant in might in some cases be preferable to a D-rated larger one, due to higher heat efficiency which will make scooping stars a lot easier.
-*'''Fuel Scoop '''- there are no stations on the way to Sagittarius A*, which means you'll have to fly into a star's corona to refill your fuel tank. Equip the best one you can afford, you don't want to spend more time next to the star than you absolutely need to. Also remember which stars can be scooped and which can't. Remembering a menomic of scoopable stars, such as KGB-FOAM, might come in handy. More on this below.
-*Bringing weapons and most utility modules is not recommended. There will most likely be no-one around to attack you while exploring, and having weapons or utility slots on board will decrease your jump range. The only utility modules that would be of any use are heat-sinks and shield boosters.
-*Shields are useful for preventing damage when landing on planets and for the occasional pirate on return to civilization. Also useful for protection from players who occasionally hang around Sagittarius A* preying on unprotected explorers.
-*[[Auto Field-Maintenance Unit]]s are handy to have but they're not essential. Your modules will deteriorate over time and it's likely you will warp into a not-nice location along the way. They don't reduce your jump range. If you can, try to equip 2 AFMUs, so that one can repair the other as well, since AFMUs can't self-heal.
-===Patience is Key===
-Sagittarius A* isn't exactly a walk down the street - it's 25,900 light years away from sol. You read that right - Twenty-five thousand light years from [[Sol]]. You won't be able to plop yourself in the seat of an Asp Explorer, hop on over to the centre of the galaxy, and get back to Earth in time for tea at grandma's. It takes, at the absolute minimum, 8 hours to get there. That's not an awfully long time, but remember that the guy that got there in 8 hours did literally nothing else but get to his destination, and 8 hours is just the time it took to get there, and it's unknown how long he spent getting back to Sol.
-If you want a profitable voyage, you'll need both time and patience and you must be able to handle being away from civilisation for a few weeks of playing until you get to the core where it's likely you'll meet up with other visiting explorers.
-===Know What You Can Scoop===
-Not every star is scoopable - only 7 star types are scoopable:
-*Red Dwarf Stars (M)
-*Orange Dwarf Stars (K)
-*Yellow Dwarf Stars (G)
-*Yellow-White Dwarf Stars (F)
-*Blue Main Sequence Stars (A, B and O)
-The sequence can be remembered with the phrase, "Oh Be A Fine Girl, Kiss Me!" or simply "KGB Foam". Be aware that T-Tauri stars are often mistaken for normal stars, as they look exactly the same - but you can tell if it's a T-Tauri star if you get into fuel scooping range and nothing happens. It will also show that it's a T-Tauri star on the system map. Be aware that sometimes you will stumble into massive swathes of space that are full of T-Tauri stars and you might run low on [[Fuel]] while inside. If this happens, search for the nearest scoopable star or if there are none nearby and you're close enough to inhabited space (<1,000ly), you can get someone with [[Fuel Transfer Drone]] to help out.
-Running out of fuel in the middle of a voyage is the worst thing that can happen to an explorer - without fuel, you can't make jumps, your modules will run out of power, and you'll be left to die. Unless the fuel rats manage to save you.
