Planets in houses
Mercury in the 4th house
A library behind the front door and stories told round the kitchen table
Mercury in the 4th house means your thinking is rooted in home, family and the past. You process life privately, often in your own space, and conversations with family, old memories and family stories shape how you see the world.

What it feels like
Home is where your mind finally relaxes. There might be books stacked by the bed, a desk in the corner of the kitchen, a drawer of letters you cannot throw away. Some of your sharpest thinking happens in pyjamas. Family stories run through you like a soundtrack, the way your grandmother said a certain word, the arguments at dinner, the jokes only your people understand.
Behind your calm face sits a busy filing cabinet, and only people you trust are handed a key. Somewhere along the line you become the family memory, the one who knows the dates and the names and the recipes. Later life often brings a love of research, history or writing things down so they are not lost. Your roots are a kind of archive, and you are its keeper.
Deep memory and a talent for making a place feel lived in. You understand where people come from.
Old family scripts can echo in your head long after they stop being useful. You are allowed to write some new lines.
You want a partner you can talk to at the kitchen table at midnight. Feeling heard at home matters more to you than grand gestures.
History, genealogy, property, writing or a family business can suit you, as can any work that makes people feel at home.
How Mercury works
Mercury is the messenger, the part of you that notices, names and passes things on. It shapes how you think, talk and learn, from the jokes you tell to the notes you scribble in margins, and its house shows where your curiosity lives. Because Mercury never strays far from the Sun, it often shares a house with your Sun or sits right next door.

Is Mercury in the 4th house good?
Warm and thoughtful, mostly. The 4th is an angular house, so Mercury is prominent here, even if its voice is mostly used in private. It often brings a strong memory and a mind that grows richer with age.
How do I know if my Mercury is in the 4th house?
You need your birth date, birth time and birth place. The houses turn a full circle every day, so without the time nobody can know which house your Mercury was in. Use the check on this page, or see your whole birth chart.
A planet within a few degrees of the next house cusp often carries the flavour of both houses, so read both pages and trust what feels true.
