Comet

A comet is an icy small Solar System body that, when passing close to the Sun, heats up and begins to outgas, displaying a visible atmosphere or coma, and sometimes also a tail. These phenomena are due to the effects of solar radiation and the solar wind upon the nucleus of the comet. Comet nuclei range from a few hundred metres to tens of kilometres across and are composed of loose collections of ice, dust, and small rocky particles. The coma and tail are much larger and, if sufficiently bright, may be seen from the Earth without the aid of a telescope. Comets have been observed and recorded since ancient times by many cultures.

Comets usually have highly eccentric elliptical orbits, and they have a wide range of orbital periods, ranging from several years to potentially several millions of years. Short-period comets originate in the Kuiper belt or its associated scattered disc, which lie beyond the orbit of Neptune. Long-period comets are thought to originate in the Oort cloud, a spherical cloud of icy bodies extending from outside the Kuiper belt to halfway to the next nearest star. Long-period comets are directed towards the Sun from the Oort cloud by gravitational perturbations caused by passing stars and the galactic tide. Hyperbolic comets may pass once through the inner Solar System before being flung out to interstellar space.

    Comet (book)

    Comet is a 1985 popular-science book by Carl Sagan and Ann Druyan. The authors describe the scientific nature of comets, as well as their varying roles and perceptions throughout history. The evolution of human understanding of comets is also detailed, and thinkers and astronomers such as Edmond Halley, Immanuel Kant, and William Huggins are discussed.

    The publication of the book was months ahead of the 1986 appearance of Halley's Comet.

    어두운 하늘을 날아다니는
    저 빛나는 별을 타고서
    긴 잠이 든 그대 품으로
    날 데려가 줄 수 있다면
    밤낮 하늘을 돌고 돌아도
    나 그대만 볼 수 있다면
    내 달콤한 단잠까지도
    다 버리고 날아올라가도 좋아
    저 빛을 따라가 혜성이 되어 저 하늘을 날아봐
    내 맘을 전하게 그대에게 데려가
    별을 내려봐 그대가 보이게 더 빛을 태워봐
    언젠가 사라져버린다 해도 내 맘을 줄거야
    까만 어둠이 밀려들어서
    긴 밤이 또 시작된대도
    나 그대만 곁에 있다면
    이 밤이 난 무섭지 않아
    밤낮 그대를 보고 또 봐도
    난 자꾸만 보고 싶어서
    내 달콤한 단잠까지도
    다 버리고 날아올라가도 좋아
    저 빛을 따라가 혜성이 되어 저 하늘을 날아봐
    내 맘을 전하게 그대에게 데려가
    별을 내려봐 그대가 보이게 더 빛을 태워봐
    언젠가 사라져버린다 해도 내 맘을 줄거야
    만약 그대가 힘이 들 때 면
    밤 하늘을 올려다봐요
    나 언제나 그대 보는 곳
    그 곳으로 날아올라가고 싶어
    저 빛을 따라가 더욱 더 높이 저 하늘을 날아봐
    내 맘을 전하게 그대에게 데려가
    나를 지켜봐 언제나 영원히 그대만 사랑해
    언젠가 사라져버릴지 몰라도 내 마음은
    다 알거야 혜성을 보면 내 사랑을 알거야
