Guest guest Posted October 4, 2005 Report Share Posted October 4, 2005 The LargestThere are 17 bodies in the solar system whose radius is greater than 1000 km. The composite above shows the Sun and the 5 largest planets at a scale of 3200 km/pixel. (Earth is the tiny spot between Jupiter and the Sun). This composite shows Earth and the remaining 11 large solar system objects at a scale of 100 km/pixel.

The BrightestThere are 12 major bodies brighter than magnitude 6 (as viewed from Earth). All of these can be seen with the unaided eye or with binoculars.

Note: Comets are often quite bright during their brief passage near the Sun. Warning: Do NOT look directly at the Sun. Looking directly at the Sun can cause severe eye damage; doing so with binoculars or a telescope will cause instantaneous and permanent blindness. The DensestThere are 11 major bodies whose density is greater than 3 g/cm3: Radius MassName (km) (kg) Dens *--------- ------- ------- ----Earth 6378 5.97e24 5.52Mercury 2439 3.30e23 5.42Venus 6052 4.87e24 5.26Adrastea 10 1.91e16 4.5 Mars 3398 6.42e23 3.94Io 1815 8.93e22 3.53Moon 1738 7.35e22 3.34Elara 38 7.77e17 3.3 Sinope 18 7.77e16 3.1 Lysithea 18 7.77e16 3.1 Europa 1569 4.80e22 3.01 *Note: Density is in grams per cubic centimeter. Note: Data for the smaller satellites are not very accurate. There are also many dense asteroids, especially the M-types. The Best Prospects for Life Name Why--------- -------Earth :-)Mars most Earth-like; more so in the pastEuropa may have liquid waterTitan complex chemistry and liquids likelyEnceladus may have liquid waterIo complex chemistry, warmer than mostJupiter long shot: warm, plenty of organic material Recent evidence of water on Mars notwithstanding, all of this remains very speculative. None of these prospects are really very good. Good arguments can be made why life (at least life as we know it) cannot exist on any of these bodies. (More about life on Europa.) But even if no life exists on other bodies in our solar system, it seem to be likely that there's probably life elsewhere in our galaxy. There are good arguments on both sides of that issue, however, the only things most scientists agree upon are that we just don't know and that more evidence is needed.
