Perseids 2026
Peak August 12-13, 2026. Up to 90 meteors/hour (IMO 2026). New Moon — zero moonlight interference. Best Perseid conditions in years.
峰值：最高每小时 90 颗流星
Total Solar Eclipse 2026
August 12, 2026. Totality path: Greenland, Iceland, Portugal, Spain. Max duration 1m58s near A Coruña. Partial eclipse visible across most of Europe. Use ISO-certified solar filters only.
Venus Greatest Eastern Elongation 2026
August 15, 2026. Venus at its greatest angular distance from the Sun. Magnitude −4.4 — brightest apparition. Best viewed in the western sky after sunset.
Deep Partial Lunar Eclipse 2026
August 27-28, 2026. ~90% of the Moon enters Earth's umbra — near-total eclipse. Visible across Asia, Australia, and the Pacific. Naked-eye observable.
2026年9月
2026年10月
Lunar Occultation of Jupiter 2026
October 6, 2026. The Moon passes in front of Jupiter. Visible from eastern Asia, Australia, and the Pacific region.
Orionids 2026
Peak October 21, 2026. Up to 20 meteors/hour. Debris from Halley's Comet. Some moonlight interference (waxing gibbous). Best after midnight facing east.
峰值：最高每小时 20 颗流星
2026年11月
Four-Planet Alignment 2026
Around November 14, 2026. Mercury, Venus, Mars, and Jupiter align in the pre-dawn eastern sky. Naked-eye visible worldwide before sunrise.
Leonids 2026
Peak November 17-19, 2026. Up to 15 meteors/hour. Fast, bright meteors with persistent trains. Best viewing after midnight in the Northern Hemisphere.
峰值：最高每小时 15 颗流星
Supermoon + Lunar Occultation of Pleiades 2026
November 24, 2026. Supermoon (perigee full moon) coinciding with a lunar occultation of the Pleiades star cluster (M45). Visible across most of the world except far western regions.
Uranus at Opposition 2026
November 25, 2026. Uranus at its brightest (~5.7 mag) — barely visible to the naked eye. Best viewed with binoculars or telescope. Best time of year to observe Uranus.
2026年12月
Geminids 2026
Peak December 14, 2026. Up to 120 meteors/hour (IMO 2026). New Moon — zero moonlight. Year's strongest shower with bright, multicolored meteors.
峰值：最高每小时 120 颗流星
December Solstice 2026
Sun reaches southernmost declination (−23.44°). Shortest day in the Northern Hemisphere.
Ursids 2026
Peak December 21-22, 2026. Up to 10 meteors/hour. Slow-moving meteors. Best from the Northern Hemisphere; circumpolar for Arctic observers.
峰值：最高每小时 10 颗流星
Biggest Supermoon of 2026
December 24, 2026. The closest full moon of the year — only 356,600 km away. Apparent diameter 34′ — 14% larger than an average full moon. Spectacular at moonrise.
2027 年事件
常见问题
- 这些天文事件日期的准确度有多高？
- 二至点和二分点日期根据 JPL DE440 星历数据计算（与 NASA 使用的行星/月球星历相同）。流星雨峰值日期遵循国际流星组织（IMO）年度日历。所有日期均为 UTC 时间。
- 我能从所在地观测到流星雨吗？
- 流星雨在全球范围可见，但辐射点高度会影响每小时可见数量。使用天工快算的恒星时计算器规划辐射点在您所在经度达到最高点的时刻。天文晨光结束后的最暗时段最为理想——使用我们的晨昏时刻计算器来确定您的观测窗口。
- 二至点和二分点有什么区别？
- 二至点是太阳达到最北（+23.44°）或最南（−23.44°）赤纬的时刻，对应最长或最短的日照日。二分点是太阳穿越天赤道（0° 赤纬）的时刻，全球各地的白天与黑夜大致等长。
- 为什么事件以 UTC 列出？
- 天文事件不受时区影响——UTC 是通用标准。通过加减您的 UTC 偏移量即可转换为当地时间。例如，中国标准时间（CST）为 UTC+8。
