FAQ
When can I see the ISS from United States?
The ISS is visible when it passes overhead after sunset or before sunrise while still lit by the Sun. Check the city grid above — “Night” and “Twilight” are the best viewing categories.
What does “visible pass” mean?
A “visible” pass typically means the spacecraft is above your horizon and illuminated by sunlight while your sky is dark enough. Visibility improves with higher maximum elevation and darker skies (lower Bortle rating).
When can I see Tiangong from United States?
Tiangong visibility works the same way as the ISS: best near dawn or dusk when it’s sunlit and your sky is darker. Switch the view selector to “Tiangong Passes” to see upcoming opportunities by city.
What is the current moon phase in United States?
The current phase is Last Quarter with approximately 43% illumination. Moonrise and moonset times differ by city.
Are there active meteor showers in United States?
Current status: Quiet. The next notable shower is April Lyrids (peak April 22). For best results, choose a city with darker skies.
Do I need special equipment to see these events?
No. The ISS and most meteor showers are best viewed with the naked eye. Binoculars can help with Moon details.
How this works
Pass predictions depend on orbital paths and sunlight geometry — a spacecraft is easiest to see when it’s sunlit while your location is in twilight or night. Higher maximum elevation generally means a brighter, longer view. Real-world visibility can still be affected by clouds, haze, and light pollution.
