수학동아 - 폴리매스
[수학 정보] 국제우주정거장(ISS) 속 수학
수학을 좋아하는 폴리매스 멤버 여러분!
안녕하세요.
도심 속 별 전망대! 과학동아천문대입니다.
3월 20일(금) 오후 7시 58분 부터 8시 5분까지 하늘의 수상한 움직임을 볼 수 있습니다.
그 정체는 바로! 국제우주정거장(ISS)!
▼3월 20일 국제우주정거장 이동 경로▼
국제우주정거장(ISS)는
19:58 남서서(SWW)쪽에서 뜨고,
20:02 금성 옆을 지나간 뒤
20:05 지구 그림자 속으로 사라져요.
▼지난 18일 촬영한 국제우주정거장의 궤적▼
▶국제우주정거장과 수학◀
국제우주정거장(ISS)는 400km 상공에서 7km/s의 속력으로 지구 주변을 돌고 있습니다.
지구의 반지름은 대략 6,400km랍니다.
그렇다면! 국제우주정거장은 하루에 지구를 몇 바퀴 정도 돌 수 있을까요?
ISS가 움직이는 둘레, 하루동안 ISS가 움직이는 거리 등등...
힌트는 여기까지!
답을 찾은 친구들은 댓글로 알려주세요~!
