첫번째 질문 태양계 내 천체들은 태양을 중심으로 공전하잔아요. 천체들이 태양 중력의 영향권 안에 있고 공전하면서, 태양의 중력과 공전하는 원심력으로 인해 일정한 궤도를 유지하고 있다고 이해하고 있습니다. 그럼 지구 중력을 벗어나기위한 제1우주속도와 같은 개념의 태양계 탈출 속도 같은 것이 있나요? 두번째 질문 우주를 배경으로한 과학소설을 보면 우주공간에서 조난을 당하거나하여 구조신호를 보내는 경우가 종종있는데 구하러 가려면 좌표가 있어야 하잔아요? 기준이 될만한 천체는 모두 무언가를 기준으로 공전하고 있고, 동서남북의 방위가 있지도 않은데 우주에서 좌표는 어떻게 알 수 있나요?
