International Space Station (ISS)
The ISS is the brightest satellite in the sky and can often be seen streaking across in just minutes—no telescope needed.
Starlink Satellite Train
After launch, SpaceX’s Starlink satellites appear in a line formation and reflect sunlight, making them clearly visible at night.
Hubble Space Telescope
Though distant, Hubble occasionally reflects sunlight just right, making it visible for a brief time in clear skies.
Tiangong Space Station (China)
China’s space station rivals the ISS in brightness and is visible from many parts of the world during specific passes.
Iridium Flares (Now Retired)
Iridium satellites were once famous for sudden bright flashes—some newer replacements still produce visible glints.
Envisat (Defunct but Reflective)
Though inactive, Envisat still orbits Earth and occasionally reflects enough light to be spotted in low-light conditions.
Genesis II (Experimental Habitat)
Launched by Bigelow Aerospace, this inflatable module can sometimes be seen as a slow-moving light in the evening sky.
