What planets are visible tonight?

Which planets are visible depends on your date and location. Venus, Jupiter, Mars, and Saturn are the four naked-eye planets that are frequently visible; Mercury is visible only in brief windows near sunrise or sunset. Enter your city above and the report will list the planets currently above the horizon after dark.

Can I see the Northern Lights tonight?

Aurora visibility depends on the Kp index and your geomagnetic latitude. At Kp 3, aurora is typically visible only near the Arctic and Antarctic circles. At Kp 5 (a G1 storm), the auroral oval expands south into the northern U.S. and northern Europe. At Kp 7+ it can reach mid-latitudes. The report above compares your latitude to the current auroral boundary in real time.

Is there a meteor shower tonight?

There are around a dozen major meteor showers each year. The report above shows the next active shower and how many days until its peak. For best viewing, look after midnight from a dark location with the shower's radiant above the horizon.

When will the ISS pass over tonight?

The International Space Station passes overhead multiple times per day, but only some passes are visible (bright, after dusk or before dawn, and above the horizon). The report above shows the next visible pass time for your location, computed from live NORAD orbital elements.

What can I see in the sky tonight from Hennef (Sieg), North Rhine-Westphalia, Germany?

Tonight from Hennef (Sieg), North Rhine-Westphalia, Germany expect a waxing crescent Moon at 9% illumination, with these naked-eye planets above the horizon after dark: Mars, Jupiter, Saturn. The night offers about 9.5 hours of true astronomical darkness.

What planets are visible tonight in Hennef (Sieg), North Rhine-Westphalia, Germany?

Tonight in Hennef (Sieg), North Rhine-Westphalia, Germany, Mars, Jupiter, Saturn are visible to the naked eye after dark, based on this location's real ephemeris for tonight.

When does darkness start tonight in Hennef (Sieg), North Rhine-Westphalia, Germany?

Astronomical darkness begins at 8:32 PM local time in Hennef (Sieg), North Rhine-Westphalia, Germany tonight, the moment the Sun drops more than 18° below the horizon and the sky becomes fully dark for faint-object observing.

Can you see the aurora tonight in Hennef (Sieg), North Rhine-Westphalia, Germany?

Hennef (Sieg), North Rhine-Westphalia, Germany is far enough from the pole that aurora only reaches overhead during a major geomagnetic storm — specifically when the planetary Kp index reaches about 5.3, a level reached only a handful of times per solar cycle.

What is the stargazing light pollution level in Hennef (Sieg), North Rhine-Westphalia, Germany?

Hennef (Sieg), North Rhine-Westphalia, Germany is a small town — typically Bortle class 1–4 (rural to excellent dark sky), where the Milky Way is usually visible on clear, moonless nights away from local lighting. These are typical ranges for this population size, not a measured reading for this exact spot — use tonight's Moon phase and the best-nights list above to time a visit away from direct lighting.

Does Hennef (Sieg), North Rhine-Westphalia, Germany's elevation help stargazing?

At 70 m you are above a meaningful fraction of the atmosphere, which reduces extinction and scintillation — the reason major observatories are sited high. Effelsberg Radio Telescope sits about 40 km from Hennef (Sieg), North Rhine-Westphalia, Germany at 319 m.

What should I plan for observing near Hennef (Sieg), North Rhine-Westphalia, Germany?

High sites reward targets that suffer most from atmosphere: planets at high altitude, faint nebulae, and the Milky Way, which culminates around 10.2° here. Cold and thinner air are the practical constraints, not the sky.

How dark does it actually get in Hennef (Sieg), North Rhine-Westphalia, Germany tonight?

About 9.5 hours of astronomical darkness (Sun more than 18° below the horizon). That is the real observing window for faint objects; brighter targets are workable from dusk onward.

Local sky character in Hennef (Sieg)

Northern mid-latitudes · northern hemisphere · 70 m elevation

The north celestial pole stands 50.8° above the horizon, so stars within 51° of it never set from here.
About 88.7% of the whole sky rises above the horizon at some point in the year from this latitude.
The Milky Way's core in Sagittarius culminates about 10.2° up, staying low, so a clear southern horizon matters.
At 70 m elevation, roughly 1% of the atmosphere's mass is already below you, which measurably reduces extinction near the horizon.

Best nights this month in Hennef (Sieg)

Calculated for these coordinates and today's date — not a fixed list.

2026-10-21 — Orionids peak — up to 20/hour
Radiant in Orion. Visible from both hemispheres. The Moon is 72% lit on peak night, so lunar interference is moderate.
2026-10-25 — Full Moon
A 99%-lit Moon washes out faint objects, but lunar terrain along the limb is at its most striking — plan bright targets and planets instead of deep sky.
2026-11-05 — Taurids peak — up to 5/hour
Radiant in Taurus. Favours the Northern Hemisphere, which includes Hennef (Sieg), North Rhine-Westphalia, Germany. The Moon is 18% lit on peak night, so lunar interference is low.
2026-11-09 — Darkest night of the coming month
The Moon is only 0% illuminated, giving the least lunar interference in the next 30 nights — the best window for the Milky Way and faint deep-sky targets from Hennef (Sieg), North Rhine-Westphalia, Germany.
