//Accessing summary

Object LS-627 is a dark D-type asteroid discovered in 0.68 through direct imaging and located in the median asteroid belt of the Smyrnia-Silesia system. It is a binary asteroid made of two similarly sized objects, named LS-627-a and LS-627-b. The two components are 116 and 121 kilometres in diameter, respectively, and orbit their centre of mass in a roughly circular pattern. The low density of LS-627 (0.85 g/cm³) hints at the possibility that at least one of the components is a comet core, captured during the inwards migration of Typhon, the main gas giant of the system. This hypothesis is not supported by orbital models, however.

Object LS-627 has undergone significant artificial alterations in the past decade. RCS thrusters have been added to the equatorial bands of both components, allowing for remote control of their axial tilt, and their surface has been polished and smoothed out with heavy mining lasers. LS-627-a (hereby referred to as MIRROR) has been covered in several ice plates, all roughly a hundred meters in size, significantly increasing the object's albedo. LS-627-b (hereby referred to as LIGHT) has been outfitted with seven low-power, high-aperture lasers emitting in blue, red and green wavelength. Spectral analysis reveals that the lasers are commercial-grade lightshow equipment imported from the Earth. The ice plates on MIRROR are carved in such a way that laser pulses are reflected from the high-albedo surface following geometric patterns that remove any glare risk for nearby vessels. Nevertheless, close approach of LS-627, if safe, is not recommended. Emission from LS-627 are visible with the naked eye from 50,000 km, while navigation telescopes can pick them up from up to two light-seconds. 

LS-627 emits on two frequencies. The main frequency, 786.7, is an open music channel. By default, it broadcasts a playlist of vintage titles, many of which are historical pieces belonging to pre-Low Age genres such as disco, hard rock or synth rock. Laser emissions from LIGHT are synched with the beats, while their colours seem to be attributed at random, though choruses and riffs are always highlighted by triple-coloured bursts. The playlist is updated every trimester. Every Friday and Saturday night, LS-627 broadcasts OPEN CHANNEL. When OPEN CHANNEL is active, the playlist is paused and passing spaceships can submit requests to the asteroid. MIRROR then plays the requests in order, with an accompanying lightshow. OPEN CHANNEL events last between two and six hours.

The auxiliary frequency, 789.7, is one-way only. It broadcasts a single message on repeat and in the clear. Transcript of the message is as follows.

Hey, Liv. The stars are a little colder without you, so I figured you'd enjoy the lights, wherever you are. See you beyond the event horizon. Yours, Maya.
