This Week's Sky at a Glance, November 29 – December 8
Si miras al cielo antes de que salga el Sol, todavía puedes ver las constelaciones del hexágono del invierno cerca del horizonte oeste. A medida que se acerca el cambio de estación, estas constelaciones (con Júpiter incluido) se van desplazando hacia el cielo de la puesta de Sol.
El cielo al anochecer tiene ya un nuevo planeta. Júpiter sale por el este en cuanto empieza a oscurecer y permanece en el cielo toda la noche. La próxima semana estará en oposición al Sol, por lo que se encuentra en el momento del año de mayor brillo y tamaño. No te lo pierdas!
