The nine planets in this solar system somewhat align once every 500 years and are grouped within 30 degrees every one to three alignments. When astrologers describe the planets as being aligned, they do not necessarily mean that all of the planets line up on a perfectly straight line. The last alignment within 30 degrees occurred in 561 B.C., and the next alignment within 30 degrees takes place in 2854.Full Answer >
The planets, with the exception of dwarf planet Pluto, lie in the same relatively flat plane because the solar system formed from a collapsing disk of spinning material 4.5 billion years ago. A cloud of material condensed into an accretion disk of matter that spun around the sun, and particles that did not coalesce into planetary bodies were blown away by strong solar winds.Full Answer >
The planets in this solar system never line up perfectly, but they will come into alignment in 2854. Each planet rotates around the sun at a different speed, and the planets form a rough alignment once every 500 years.Full Answer >
The surface temperatures of the solar system's planets are dependent on how close each planet is to the sun. Planets that have atmospheres are better able to retain heat from the sun, affecting the planet's surface temperature.Full Answer >
