Janhunen has plans for the dish-shaped satellite, too—he envisions it as over a mile long and with thousands of interconnected cylindrical structures on its surface to house humans, and also to provide space for other necessities such as agriculture and recreational spaces. He also imagines a pair of giant mirrors for harnessing the sun's energy on either side of the satellite, giving the overall structure a clam-like shape. He also envisions starting off with a population of 50,000 people.
This may worth something:

SpaceX's latest Starlink launch puts 60 more satellites into orbit | Metro News
The private space company sent a reusable Falcon 9 rocket on its record-breaking eighth trip to the edge of space to deliver the payload.
The launch was initially scheduled to take place on January 18, but was pushed back due to poor weather conditions.
The plan has raised some concerns from astronomers, so SpaceX has moved the spacecraft further away from Earth and given them a non-reflective coating to try and appease stargazers.

A Bucknell professor and a university researcher are part of an international research team that discovered a new, low-mass binary planetary system located 450 light years from Earth.
Working with researchers from the Center for Space and Habitability and NCCR PlanetS at the University of Bern in Switzerland, Bucknell physics and astronomy professor Katelyn Allers and postdoctoral researcher Blake Pantoja released a study recently in The Astrophysical Journal Letters.
Dealing with celestial scrap - Removing space junk | Science & technology | The Economist
H UMAN BEINGS are messy. They tend to leave rubbish behind them wherever they go—and to expect someone else to clear that rubbish up. This is true even in outer space. The problem of orbiting debris, and the concomitant risk of it colliding with and damaging an active and probably expensive satellite, has been around for a while. But it is rapidly getting worse. There may now be as many as 1m bits of debris measuring 1cm or more across in orbit.

In the short term, satellite owners can, literally, dodge the problem—as long as their craft are fitted with appropriate thrusters. Mr Oltrogge's day job is to arrange for that to happen, for he also works for AGI , an American firm that develops (among other things) software which helps satellite operators sidestep such collisions. In the longer term, however, more radical action will be needed.

Even so, Janhunen's proposal comes with its own caveats that could work against a successful Ceres colony, an outside researcher pointed out.

Beyond the cylinders and their massive disk frame, the colony's main features will be two enormous glass mirrors, angled at 45 degrees relative to the disk in order to reflect just enough natural sunlight into each habitat. Part of each cylinder will be devoted to growing crops and trees, planted in a 5-foot-thick (1.5 meters) bed of soil derived from raw materials from Ceres, Janhunen wrote. The natural sunlight should keep them growing strong.
Astronomers Spot Bizarre Cosmic System with Three Suns and One Planet Revolving in Skewed Orbit |
Our universe is full of mysteries! Having observed our own solar system and the ones located nearby (in cosmic terms), we do know that celestial objects revolve around the largest body in their proximity, usually in the same plane. While planets orbiting a single star, as is the case with our solar system, is a familiar concept, there do exist interesting anomalies.
A team of astronomers has recently discovered one such bizarre exoplanet (planet outside our solar system) with not one, not two, but three companion stars! The research, led by scientists from NASA's Exoplanet Science Institute, has estimated that this system is located about 1,800 light-years away from us. Its discovery was recently announced at the 237th meeting of the American Astronomical Society.
