"Sky spread" is the angular width the selected planets occupy in Earth's sky (geocentric ecliptic longitude) — this is what a real "planetary alignment" news story means. "Heliocentric spread" plus "plane deviation" is the stricter test for a true syzygy: same Sun-relative angle and the same orbital plane. Because every planet has a different orbital inclination, plane deviation rarely reaches zero — a perfect 3D line-up is far rarer than a loose visible conjunction. Click a planet to follow it; drag to orbit the view, scroll to zoom.

Drag = orbit · scroll = zoom · click a planet = follow
