How far is planet 9 au
Earth's orbit around the Sun is an ellipse. The semi-major axis of this elliptic orbit is defined to be half of the straight line segment that joins the perihelion and aphelion. The centre of the Sun lies on this straight line segment, but not at its midpoint. Because ellipses are well-understood shapes, measuring the points of its extremes defined the exact shape mathematically, and made possible calculations for the entire orbit as well as predictions based on observation. In addition, it mapp… WebThe parallax of a celestial body can be used to find an approximate distance using the formula. Where D is the actual distance measured in parsecs and p is the observed parallax angle measured in arcseconds. This formula is used in our calculator. A parsec is defined as the distance at which an object has a 1-arcsecond stellar parallax.

At this location, Planet Nine would be approximately 630 AU from the Sun, with right ascension close to 2 h and declination close to −20°, in Cetus. In contrast, if the putative planet is near aphelion it would be located near right ascension 3.0 h to 5.5 h and declination −1° to 6°. Meer weergeven Planet Nine is a hypothetical ninth planet in the outer region of the Solar System.
