Den fik senere navnet Titan, opkaldt efter en k\u00e6mpe fra de gamle gr\u00e6ske sagn.<\/p>\n<\/div>\n<p>Titan var sandelig en k\u00e6mpe \u2013 den n\u00e6stst\u00f8rste m\u00e5ne i solsystemet. Men selv i dag er den en verden fuld af mysterier. Dens overflade er skjult bag et t\u00e6ppe af orange t\u00e5ge.<\/p>\n<p>Forskere ved, at dens t\u00e6tte atmosf\u00e6re hovedsageligt best\u00e5r af nitrogen, ligesom p\u00e5 Jorden. Den indeholder ogs\u00e5 metan, den gas, vi forbr\u00e6nder i vores huse og fabrikker.<\/p>\n<p>Men overfladetemperaturen er \u2013180 \u00b0C, hvilket er koldt nok til, at isen bliver s\u00e5 h\u00e5rd som sten. Det er sandsynligvis for koldt til, at der kan eksistere liv, selvom der muligvis findes et hav dybt under jordoverfladen.<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"2105\" data-credit=\"ESA-D.
