ISS Orbit Tracker 3D Explorer vs Earth 3D Globe and Solar System
The ISS Orbit Tracker 3D Explorer teaches ground tracks and LEO inclination in one page load - 0 MB, USD 0, no account. Earth 3D Globe shows a static day/night terminator but no moving satellite; Solar System 3D animates all eight planets but does not isolate one LEO station's ground track.

Where ISS Orbit Tracker wins
ISS Orbit Tracker wins when you need ground tracks, inclination 51.64 deg, and published ISS figures - mean altitude 408 km, period 92.9 min, speed 7.66 km/s, 15.5 orbits per day - in one WebGL lesson. Everything runs locally. The orbit-phase slider and ground-track toggle sit on one LEO lesson; Earth 3D Globe keeps a static day/night ground view and Solar System keeps the multi-planet layout.
Where Earth 3D Globe wins
Earth 3D Globe wins when you need a day/night terminator driven by clock time on a static ground view - useful for "where is the Sun right now?" literacy. It does not add a moving satellite or an inclined orbit ring.
Where Solar System wins
Solar System 3D Explorer wins when you need all eight planets orbiting together, comparative sizes, and a speed slider across the whole system. It answers "what does the solar system layout look like?" rather than "what path does one LEO station trace over Earth?"
A reasonable rule
As a reasonable rule, use ISS Orbit Tracker for ground-track and inclination literacy in under a minute; use Earth 3D Globe for static day/night on the ground; use Solar System for the big-picture planet layout; use a dedicated pass-predictor app for tonight's real ISS flyover. The NASA figures in the panel - 408 km altitude, 92.9 min period, 7.66 km/s, 51.64 deg inclination, 15.5 orbits per day - stay accurate either way.
