Major Astronomical & Planetary Events: December 1–7, 2025
Written by Mia Astrology
Dear friend, the skies are easing into winter with quiet strength this week. We’re not under massive firework meteor showers yet—but there’s meaningful celestial movement: a Supermoon Full Moon, Mercury at its best morning appearance, and the Moon brushing past giant Jupiter. These shifts may feel subtle, but what stirs beneath the surface now will set the tone for December’s deeper magic.
🌕 Full Moon in Gemini — December 4, 2025
The Moon is full, bright, and emotionally charged in informative Gemini. But with winter closing in, this Full Moon carries themes of clarity, connection, and conversations you’ve been avoiding.
🔍 What this means
- The “Supermoon” tag means the Moon is slightly closer to Earth—energy feels bigger.
- Gemini asks you to think, write, speak, share. Gemini-Full Moons often highlight connections, siblings, communication channels.
- Because Jupiter is nearby later in the week, the emotional amplification is real.
✅ Most affected signs
Gemini, Sagittarius, Virgo, Pisces
💡 What’s good to do
- Journal a conversation you’ve been itching to have.
- Record your thoughts for 10 minutes at moonrise.
- Look at your communication habits. Who do you need to call or write?
🚫 What to avoid
- Scattered thinking. Gemini can flit—ground it by writing one clear intention.
- Gossip or half-truths. Honesty matters now.
🎯 Intuitive message
Your words have weight. What you say now could echo all month. Let them be true.
🌙 Moon Near the Pleiades — Night of December 4
On the night of the Full Moon, the Moon drifts near the Pleiades star cluster in the evening sky. It’s a visual delight—and symbolically rich.
✨ Symbolic message
The Pleiades are star-stories of navigation and homecoming. When the Moon nears them during a Full phase—it’s a reminder that coming home to yourself is power.
🚀 Mercury at Greatest Elongation West — Morning of December 7
Mercury reaches its best morning visibility of the year. Look to the east-southeast just before sunrise—Venus may still be there, but Mercury is the star this morning.
✅ Why it matters
- Peak visibility = clarity of communication.
- After months of Mercury’s retrograde zones and shadow periods, you now have an energetic “green light” to speak, negotiate, pitch, express.
💡 What to do
- Send that email or proposal you’ve been refining.
- Speak up in a meeting. Your voice is aligned with the stars.
🚫 What to avoid
- Impulsive texts or messages without thought. Even Mercury’s speed still needs presence.
🎯 Intuitive message
You’re ready to articulate your next phase—not just think it. Let the planet of mind guide you.
🌖 Moon Near Jupiter — Evening of December 7
Just after sunset on December 7, the Moon approaches Jupiter in the eastern sky. A lovely pairing, visible with the naked eye under clear skies.
✨ What you’ll feel
- Big picture getting bigger.
- A sense of “more” approaching—growth, hope, revival.
- A nudge to align your vision with your next steps.
🎯 Intuitive message
The Moon reflects, Jupiter expands. Together they say: your aspirations deserve air. Give them space.
🪐 Planetary Under-Currents
- Sun in Sagittarius: the season of exploration, truth-seeking, vision.
- Mercury at best-morning position: clarity and mind-light.
- Venus still in Scorpio: depth, sensuality, values in motion.
- Mars in Sagittarius: action in rhythm with the season of seeking.
- Retrogrades continuing: Saturn Rx & Neptune Rx (Pisces), Uranus Rx (Gemini). These continue to urge inner alignment rather than external spectacle.
💡 Intuitive takeaway
Even though external “big events” are limited—this week is a groundwork week. For your spirit. For your story. For your next chapter to feel aligned when you step in.
🌟 How Each Element Signs Work This Week
🔥 Fire Signs (Aries, Leo, Sagittarius)
The Full Moon wants your story told. Use the clarity of Mercury to express it. And the Moon-Jupiter pairing to expand it.
🌍 Earth Signs (Taurus, Virgo, Capricorn)
Grounded energy returns. Use Gemini Full Moon to review your networks, train your ideas, connect with your systems.
🌬 Air Signs (Gemini, Libra, Aquarius)
This is your week. Big Moon in your sign’s opposite. Speak, share, shine—but don’t lose your stillness.
💧 Water Signs (Cancer, Scorpio, Pisces)
Depth returns. Mercury rising in the morning sky gives you clarity—let your intuition catch the light, then act.
