All astrologers are familiar with the Moon’s nodes, and all planets, not just the Moon, have nodes.The nodes are the points where the path of the planetcrosses the ecliptic plane. Unlike the moon’s nodes, the geocentric north and south node of planets arenot necessarily directly opposite to each other. Just as there is a mean and true Moon’s node, there are true and mean planetary nodes. The true nodes are referred to as osculating nodes. However, unlike the Moon’s nodes, typically the osculating node positions arenearly identical to the mean node positions so it makesalmost no difference which one you select. Also, heliocentric nodes are sometimes used in the geocentricchart rather than geocentric nodes. Although this may at first not seem intuitively reasonable, the heliocentric node is preferred by some astrologers. In Sirius 1.2,you can select any of these three options. The glyphs of the planetary nodes look similar to the glyphs of the Moon’s North Node and South Node, except that a small glyph of the planet is contained within the nodeglyph so the glyphs are easy and simple to recognize.
