Stability of the Solar System one point, the two may fall into sync, at which time Jupiter's constant gravitational tugs could accumulate and pull Mercury off course with 1–2% probability, 3–4 billion years into the future. This could eject it from the Solar System altogether or send it on a collision course with Venus, the Sun, or Earth. Another example is Earth's axial tilt which, due to friction raised within Earth's mantle by tidal interactions with the Moon (see below), will be rendered chaotic at some point between 1.5 and 4.5 billion years from now. Objects coming from outside the solar system can also affect
Solar eclipses on the Moon portion of the eclipse was rising. Eclipses were more frequent, tens of millions of years later, eclipses became less numerous as the lunar orbit slowly moved away from the Earth. The view of the sun, even its chromosphere was blocked by the Earth. Around some hundreds of millions of years ago, the Earth blocked all of the Sun's chromosphere, totality was slightly longer than the partial portion. At the same time there were more partial eclipses on the Moon. As the Moon recedes about 3 cm each year, eclipse totality length slowly shrinks and the partial portion slowly lengthens. The
