What would happen if it took Earth longer to rotate?

Our days would be longer for a start, darkness would fall more slowly and the night would last longer. The surface temperature range would also be greater, as more time during the night would allow the surface to cool more, while longer days would cause it to heat up more. this may well impact on weather conditions. The Earth did actually spin faster many years ago, but has gradually slowed down over time thanks to the drag caused by the moon.


Which planets summer lasts 21 earth years?

Uranus and Neptune have summer seasons that last approximately 21 Earth years due to their long orbital periods. This is because both planets have unique axial tilts and orbits that create extreme seasonal variations.


How long will the sun's red giant stage last for?

The sun's red giant stage will last for 1 or 2 billion years.


When will all the planets line up in a line?

The chances of the planets ever lining up are so statistically improbable that it is safe to say it will never happen. The actual chances of the planets ever lining up has been calculated to be about once every 8.6 x 1046 years. (That's once every 86 billion, trillion, trillion, trillion years.) Since the Sun will be gone in about 10 billion years, it is impossible for this to happen.


How often do the planets aline?

The planets do not align frequently. A perfect alignment of all planets in our solar system is very rare due to their different orbits and speeds of rotation. The last time all the planets aligned in a straight line was in 561 BC, and such a perfect alignment won't happen again for millions of years.
