Four stars in the bowl, three in the handle, spanning 25°. Five of the seven — everything except Dubhe and Alkaid — are physically related: they drift through space together as the Ursa Major moving group, about 80 light-years away. The two end stars are unrelated strangers travelling the other way, which means the Dipper is slowly coming apart. In 100,000 years the handle will be bent and the bowl spilled.
Look hard at the bend in the handle. Mizar (magnitude 2.23) has a companion, Alcor (3.99), 11.8 arcminutes away — about a third of the Moon's width. Splitting them by eye was a traditional eyesight test across Arabia and Europe. They are not a line-of-sight coincidence: Gaia puts both at 82–83 light-years and they are gravitationally bound. Between them, the pair contains six stars.
The handle is not straight — it curves. Keep that curve going past Alkaid for 30.7° and you arc to Arcturus: magnitude −0.05, the brightest star north of the celestial equator, a K-type giant 37 light-years away and visibly orange. It is also a halo star, ploughing through the galactic disc at 122 km/s on a path that will take it out of our neighbourhood entirely.
Carry the same curve 32.8° further and spike to Spica — magnitude 0.98, blue-white, and a completely different kind of object: two B-type stars orbiting each other every four days, close enough to pull one another into eggs. Arc to Arcturus, spike to Spica. Two hops, 63°, and you have crossed a third of the visible sky.
Back to the bowl. Merak and Dubhe, the two on the outer edge, are 5.4° apart and aim at Polaris, 28.7° beyond Dubhe. Because Polaris's altitude equals your latitude, this line is also an instrument: it tells you which way is north and how far up the planet you are standing.
The bowl's other diagonal punches a hole in its bottom. From Megrez, where the handle joins, through Phecda at the far corner — those two are 4.5° apart — and on for eleven times that gap, 51°, to Regulus, the heart of Leo. Pointers up for Polaris, diagonal down for Regulus: the same bowl, two directions.
The Dipper never sets from here, and the altitude readout is the proof: over twelve hours it dips and climbs but does not reach zero. The rule is simple — anything whose declination is greater than 90° minus your latitude is circumpolar. Six of the seven Dipper stars are north of +49°, so from the mid-northern latitudes the whole shape stays up all night; Alkaid, the last star of the handle at +49.3°, is the one that grazes the horizon first as you travel south.
