This entity's magnetic field standoff distance is only 1.6 times its own radius, making it so that it cannot support radiation belts.
This entity's magnetic field standoff distance is only 1.6 times its own radius, making it so that it cannot support radiation belts. When a probe was deflected by this object, scientists determined that its density was 5,430 kilograms per cubic meter. Thus, scientists determined that42 percent of this object is composed of iron and that it is the most iron-rich object in the SolarSystem. The Arecibo satellite fired a pulse at this object and found that its rotational period was58.6 days, establishing that it has a 3:2 spin-orbit resonance. While studying this object, Urbain Le Verrier found that a value of 43 arc-seconds per tropical century characterizes the rate of precession of its perihelion. Einstein's theory of general relativity explained that precession, causing astronomers to reject the idea that the hypothetical planet Vulcan was perturbing its orbit. Mariner 10 has visited, for 10 points, what planet, the closest one to the Sun?
