Partiendo de la Estrella Polar, ¿qué constelación podremos ubicar por enfilaciones de la Osa Mayor?Starting from the Pole Star (Polaris), which constellation can we locate using alignments from Ursa Major?

Show the answer

Correct answer: c) Cassiopeia.

Why it is correct

Extending the line from Ursa Major (specifically from Megrez / Delta Ursae Majoris or the Pointers) through Polaris to an equal distance on the opposite side of the celestial pole locates the W of Cassiopeia.

Why the others are not

  • a) Orion is an equatorial constellation far from the north celestial pole.
  • b) The Southern Cross lies near the south celestial pole.
  • d) The classic Ursa Major → Polaris alignment leads directly to Cassiopeia opposite the pole.

How to work it out in the exam

  1. Alignment from Ursa Major through Polaris extended to the opposite side: locates Cassiopeia.
