Jupiter is unmissable at the moment. Just look south (ish) during the night and it's easily the brightest "star" in view. Unlike real stars, it doesn't twinkle (one way of telling a planet from a star). Something to do with the fact that planets don't shine by their own light but by reflected sunlight. Get yer binoculars out, get 'em in really sharp focus and be gobsmacked by Jupiter's moons. You can nearly always see at least two and they are always to the left and/or right of the planet, never above or below. Magic.
