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 Setagaya, Tokyo, Japan?

Tonight from Setagaya, Tokyo, Japan expect a waxing crescent Moon at 2% illumination, with these naked-eye planets above the horizon after dark: Mars, Saturn, Jupiter. The night offers about 9.8 hours of true astronomical darkness.

What planets are visible tonight in Setagaya, Tokyo, Japan?

Tonight in Setagaya, Tokyo, Japan, Mars, Saturn, Jupiter are visible to the naked eye after dark, based on this location's real ephemeris for tonight.

When does darkness start tonight in Setagaya, Tokyo, Japan?

Astronomical darkness begins at 6:35 PM local time in Setagaya, Tokyo, Japan 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 Setagaya, Tokyo, Japan?

Setagaya, Tokyo, Japan is far enough from the pole that aurora only reaches overhead during a major geomagnetic storm — specifically when the planetary Kp index reaches about 9, a level reached only a handful of times per solar cycle.

What is the stargazing light pollution level in Setagaya, Tokyo, Japan?

Setagaya, Tokyo, Japan is a mid-sized urban area — typically Bortle class 5–6 (bright suburban sky), where major constellations are workable but the Milky Way is washed out. 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 Setagaya, Tokyo, Japan's elevation help stargazing?

At 44 m you are above a meaningful fraction of the atmosphere, which reduces extinction and scintillation — the reason major observatories are sited high. Nobeyama Radio Observatory sits about 111 km from Setagaya, Tokyo, Japan at 1350 m.

What should I plan for observing near Setagaya, Tokyo, Japan?

High sites reward targets that suffer most from atmosphere: planets at high altitude, faint nebulae, and the Milky Way, which culminates around 25.4° here. Cold and thinner air are the practical constraints, not the sky.

How dark does it actually get in Setagaya, Tokyo, Japan tonight?

About 9.8 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.

Tonight's sky above Setagaya, Tokyo, Japan

Whether tonight is a good night for stargazing from Setagaya, Tokyo, Japan comes down to four real things: the Moon phase, cloud cover, which planets are up, and the current Kp index.

Local sky character in Setagaya

Northern mid-latitudes · northern hemisphere · 44 m elevation

The north celestial pole stands 35.6° above the horizon, so stars within 36° of it never set from here.
About 79.1% 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 25.4° up, staying low, so a clear southern horizon matters.
At 44 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 Setagaya

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 100%-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 Setagaya, Tokyo, Japan. The Moon is 18% lit on peak night, so lunar interference is low.
2026-11-08 — 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 Setagaya, Tokyo, Japan.
