It is a nearly perfect sphere of hot plasma,^[14][15] with internal convective motion that generates a magnetic field via a dynamo process.^[16] It is by far the most important source of energy for life on Earth.]]> 2018-01-09 16:33:21 UTC https://padlet.com/304881/b42oeg4hquqx/wish/219825699 304881 https://padlet.com/304881/b42oeg4hquqx/wish/219827539 Gravity, or gravitation, is a natural phenomenon by which all things with mass are brought toward (or gravitate toward) one another, including objects ranging from atoms and photons, to planets and stars. Since energy and mass are equivalent, all forms of energy(including light) cause gravitation and are under the influence of it]]> 2018-01-09 16:36:00 UTC https://padlet.com/304881/b42oeg4hquqx/wish/219827539 304881 https://padlet.com/304881/b42oeg4hquqx/wish/219828972 A star is type of astronomical object consisting of a luminous spheroid of plasma held together by its own gravity.

The larger ones have also been called planetoids. These terms have historically been applied to any astronomical object orbiting the Sun that did not show the disc of a planet and was not observed to have the characteristics of an active comet.]]> 2018-01-09 16:41:52 UTC https://padlet.com/304881/b42oeg4hquqx/wish/219831359 304881 https://padlet.com/304881/b42oeg4hquqx/wish/219832266 A comet is an icy small Solar System body that, when passing close to the Sun, warms and begins to release gases, a process called outgassing. This produces a visible atmosphere or coma, and sometimes also a tail. These phenomena are due to the effects of solar radiation and the solar wind acting upon the nucleus of the comet.]]> 2018-01-09 16:43:07 UTC https://padlet.com/304881/b42oeg4hquqx/wish/219832266 304881 https://padlet.com/304881/b42oeg4hquqx/wish/219833358 2018-01-09 16:44:49 UTC https://padlet.com/304881/b42oeg4hquqx/wish/219833358 304881 https://padlet.com/304881/b42oeg4hquqx/wish/219833896 Meteoroids are significantly smaller than asteroids, and range in size from small grains to one-meter-wide objects.^[2]Objects smaller than this are classified as micrometeoroids or space dust.^[2][3][4] Most are fragments from comets or asteroids, whereas others are collision impact debris ejected from bodies]]> 2018-01-09 16:45:46 UTC https://padlet.com/304881/b42oeg4hquqx/wish/219833896 304881 https://padlet.com/304881/b42oeg4hquqx/wish/219834876 The Moon is an astronomical body that orbits planet Earth, being Earth's only permanent natural satellite.
