DRAG TO ORBIT

CALCULATED · NOT AN OBSERVATION · CATALOGUED RADIUS · DENSITY 1.18 G/CM³ · RADIUS 236 KM · LIT FROM WHERE THE SUN IS

Drawn from the catalogued radius and from the same properties the picture at the top of this page uses, at the distance a flight to it would stop. Drag it, or use the arrow keys, to look from another direction. The stars behind are the 498,631 this catalogue holds real distances for, at their real positions and drawn from where the camera actually is — so the constellations are wrong, and that is the point. This is the sky from there, not the sky from here.

What it takes to see Miranda for yourself. Everything in this part of the page is worked out for a real horizon, a real night and the equipment you say you have.

The raw catalogue values, as the source published them, with the error bars where one was published — sorted by what each set of figures is about rather than by the order they happened to be stored in.

WHAT KIND OF THING IT IS

What the object is in itself, rather than how it happens to look from here.

THE ORBIT

The shape of the path, where the object sits on it, and the instant those figures were true of. An orbit is a fit to observations and drifts away from the real one either side of its epoch.
