As is known, the Moon’s gravitational field presents significant differences from that of the Earth. In the case of orbits around the Moon, it is necessary to consider high orders of the selenopotential. We show that using a selenopotential of order and degree yields results very similar to those obtained with a potential. We search for initial conditions with the highest possible inclination, still within the range of nearly frozen orbits, which are those predicted for the Garatéa-L mission. This mission is planned to have a perilune altitude of 30 km and an apolune altitude of 300 km. We found near-frozen polar orbits around the Moon by slightly modifying the perigee altitude of the nominal orbit predicted by the mission from 30 km to 125.149 km. We also found a region of inclinations of possible interest to the Garatéa-L mission that contribute to keeping the perilune argument librating and the eccentricity frozen, maintaining the 30 km perilune altitude for at least one year (near-frozen orbit). 000163299 536__ $$9info:eu-repo/grantAgreement/ES/DGA/E24-23R$$9info:eu-repo/grantAgreement/ES/MICINN/PID2020-117066GB-I00 000163299 540__ $$9info:eu-repo/semantics/embargoedAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000163299 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000163299 700__ $$0(orcid)0000-0002-7620-4523$$aCasanova, Daniel 000163299 700__ $$aLeão, Lucas L. 000163299 773__ $$g(2025), [9 p.]$$pEur. phys. j., spec. top.$$tEuropean Physical Journal-Special Topics$$x1951-6355 000163299 8564_ $$s14798458$$uhttps://zaguan.unizar.es/record/163299/files/texto_completo.pdf$$yPostprint$$zinfo:eu-repo/date/embargoEnd/2026-08-17 000163299 8564_ $$s1253872$$uhttps://zaguan.unizar.es/record/163299/files/texto_completo.jpg?subformat=icon$$xicon$$yPostprint$$zinfo:eu-repo/date/embargoEnd/2026-08-17 000163299 909CO $$ooai:zaguan.unizar.es:163299$$particulos$$pdriver 000163299 951__ $$a2025-10-24-16:56:43 000163299 980__ $$aARTICLE
