"Últimos Resultados da Sonda Huygens em Titã"
Titã é o maior satélite do planeta Saturno. É um objecto único no Sistema Solar, pois tem uma atmosfera muito densa, composta principalmente de N2 (azoto molecular) com algum CH4 (metano). Até há pouco tempo, a sua superfície estava desconhecida, pois existe uma bruma global na atmosfera que impede que a superfície se veja. No passado dia 14 de Janeiro, a sonda europeia Huygens desceu na atmosfera de Titã e aterrou. Foi uma aventura fantástica e muito bem sucedida. Neste palestra explicarei mais sobre a missão e sobre todos os primeiros resultados.

Existem 17 corpos no sistema solar cujo raio é maior que 1000 Km.
