Their Jupiter in your 3rd house

Talking to them teaches you something

In synastry, you place one person's planets into the other person's houses. When someone's Jupiter, where you grow, falls in your 3rd house, Voice, that part of them shows up in the part of your life about communication, siblings, learning, neighbourhood.

What it's like

You come off the phone having learned a thing you didn't know you wanted to. This person encourages your curiosity and makes your voice more confident.

The good

They make you more curious and expressive

The tension

Big talk can promise more than gets done

It depends who they are

The same placement plays out differently with a partner, an ex or your mum.

If they're your partner

Talking to them teaches you something

This person sends you articles and leaves books on the bedside table. Conversation is generous and curious, with a tendency to run long.

If they're a crush

They make talk effortless

Chat with this person flows and grows: long messages, in-jokes and ideas that keep stacking up. You enjoy their curiosity.

If they're an ex

They filled your head with ideas

This person gave you books, plans, theories and reasons to say yes. Great fuel for learning, and plenty of it never left the group chat.

If they're a friend

They fill your head with good ideas

Every chat with this person leaves you with a book, a plan and a new word. They make learning feel fun and everyday conversation worthwhile.

If they're family

They talk up your ideas

This person listens to your plans and sees potential in them. Chats with them leave you feeling wiser and slightly more ambitious.

The other way round: Your Jupiter in their 3rd house

You expand how they communicate

Your Jupiter in this person's 3rd makes every chat a bit bigger. They read more, write more and say yes to the course or the podcast you recommended.

About Jupiter

Jupiter is expansion: luck, optimism, generosity and the feeling that more is possible. It makes things bigger, which is lovely for good things and less lovely for overcommitment.

About the 3rd house, Voice

The 3rd house is your everyday mind and mouth: chats, texts, short trips, siblings and the streets you walk every day. It's how you learn, and who you gossip with while you do.
