The following are some of the important features (Craters, Mountain ranges, Valleys, etc) along the Terminator line.

  • Aristoteles – A large impact crater in the lunar northern highlands.

  • Eudoxus – Prominent crater near Aristoteles, with terraced walls.

  • Montes Caucasus – Mountain range separating Mare Serenitatis and Mare Imbrium.

  • Vallis Alpes (Alpine Valley) – Long valley cutting through Montes Alpes.

  • Montes Alpes – Mountain range bordering Mare Imbrium to the northeast.

  • Mare Frigoris – Long lunar “sea” stretching across the northern hemisphere.

  • Mare Serenitatis – Large lunar mare formed by ancient volcanic activity.

  • Cassius – Crater near the Caucasus Mountains with a worn appearance.

  • Archimedes – Large circular mare-flooded crater in Mare Imbrium.

  • Montes Archimedes – Small mountain range near Archimedes crater.

  • Mare Imbrium – One of the Moon’s largest maria, formed by a giant impact.

  • Montes Apenninus – Major mountain range forming the southeast rim of Mare Imbrium.

  • Mare Vaporum – Small lunar mare located between Serenitatis and Imbrium.

  • Hipparchus – Large, ancient, heavily worn crater.

  • Albategnius – Prominent crater with a central peak, named after the Arab astronomer.

  • Ptolemaeus – Huge, old walled plain crater, nearly 150 km across.

  • Alphonsus – Famous crater with rilles and dark patches, associated with past volcanic activity.

  • Arzachel – Well-preserved crater with a central peak near Alphonsus.

  • Rupes Recta (Straight Wall) – Long linear fault on Mare Nubium (appears as a “straight cliff”).

  • Werner – Small crater near Stöfler, with sharp terraced walls.

  • Aliacensis – Crater near Werner, moderately eroded.

  • Barocius – Large old crater in the southern highlands.

  • Maurolycus – One of the largest southern hemisphere craters, highly eroded.

  • Stöfler – Ancient, huge crater with overlapping impacts.

  • Deslandres – Vast walled plain, partly ruined by later impacts.

  • Orontius – Old southern crater, overlapped by more minor impacts.

The moon image is captured using an 8-inch Dobsonian Telescope equipped with a 25-mm eyepiece and a mobile phone.
