Mars(火星)is a planet and is the 4th closest planet to the Sun. The distances from the Sun to Mars is more than 141 million miles. Mars is the largest planet in the solar system(太阳系), which makes Mars the 2nd smallest planet in the solar system. Mars is one of the four plane...
His rule was where α i is the major semi-axis of the orbit of the ith planet from the Sun. Titius's law represents the distances of the then known planets with an accuracy of a few per cent, provided that (i) for Mercury, we take i= −∞ instead of i=1 and (ii) the ...
They found, on the basis of the Doppler-Fizeau principle, that the outer portions of Saturn’s ring system rotate more slowly than the inner portions. The measured speed proved to be equal to the speeds Saturn’s satellites would have if they were located at the same distances from the ...

travel on nearly circular paths about the Sun. Most extrasolar giant planets with orbital periods longer than two weeks haveelongatedorbits. Models of planetary formation suggest that giant extrasolar planets detected very near their stars formed at greater distances and migrated inward as a result of...
It is critical to note that the distances between planets becomes greater with increasing distance from the sun. Viewed from above and with the orbits of each planet made magically visible, the solar system would not resemble a series of evenly spaced concentric rings. Instead, you would see th...
of Hawaiian volcanoes, and was created by eruptions of lava that flowed for long distances before solidifying. Mars also has many other kinds of volcanic landforms, from small, steep-sided cones to enormous plains coated in hardened lava. Some minor eruptions might still occur on the planet ...
The Planets and The Solar SystemOur earth is also a planet. The earth and eight other planets move around the Sun. The planets appear bright because they reflect the light of the Sun. The nine planets, in order of increasing distances from the Sun are Mercury (Budha), Venus (Shukra),...
In October 2005, NASA announced that the Hubble Space Telescope had photographed two new objects that may be satellites of Pluto. Observations suggest that the satellite candidates, provisionally named S/2005 P1 and S/2005 P2, orbit Pluto at distances of about 49 000 km and 65 000 km respecti...
