Conjunction
Earth is the third planet from the Sun.
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.
Two or three planets align from time to time, but an alignment of all the planets would never happen. The chances of the planets ever lining up in our lifetime is zero. The chances of the planets ever lining up has been calculated to be about once every 8.6 x 1046 years. That's 86 billion, trillion, trillion, trillion years. The age of the Solar System is only about 4.6 x 109 years or 4.6 billion years and the Universe is only about 13.75 billion years old.
The Moon orbits Earth, so it does not typically "line up" with planets. However, during certain alignments, the Moon can appear close to planets in the sky from our perspective on Earth, such as lining up with Jupiter or Mars.
No. We were all supposed to die 10 years ago as well as 5 or 6 other occasions I can think of.
