Frequently asked questions
How fast does Thor Agena D R/B travel?
Its speed follows from its orbit: one revolution every 100 minutes. Low-orbit satellites move at roughly 7.5 km per second (27,000 km/h); the higher the orbit, the slower the satellite. The live strip above shows the current ground speed.
Can I see Thor Agena D R/B from the ground?
Usually only with binoculars or a camera. Small satellites are faint; the pass predictor above marks passes where the geometry is right (dark sky, sunlit satellite), but a dark site and knowing exactly where to look matter.
Why does the position keep moving across the map?
The satellite moves several kilometers every second while Earth rotates underneath it, so each orbit’s ground track lands west of the last one. The orbit itself is fixed in space; the map shows where it is above the turning Earth.
Where does the live position come from?
From the object’s published orbital elements (NORAD general perturbations data via CelesTrak), propagated with the SGP4 model in your browser. The same data drives the satellite layer on the EarthBrowser globe. Elements are refreshed daily, which keeps positions good to a few kilometers.
