How many planets are there today?
In our solar system, there are eight recognized planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Neptune, and Uranus. The total number of planets outside of our solar system can only be hypothesized, but evidences of new planets are being discovered at an ever increasing rate.
How many planets are there in our solar system, including the keyword "9 planets"?
Well the number of planets in our solar system is actually a bit different now. Remembering that there used to be 9 planets is perfectly okay, but today we recognize only 8 planets in our solar system. It's all a part of the ever-changing nature of our beautiful universe.
What planets are in the constellation ursa major?
There are no planets in the constellation Ursa Major. This constellation is home to many stars, including the well-known star cluster known as the Big Dipper or the Plough. However, planets in our solar system can be seen passing through or near Ursa Major at different times due to their orbits.
What planets have astronauts visited?

Could planets align?
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.
What other planets did Armstrong saw?
He may easily have seen all of the planets in our solar system at one time or another, but the only one he or anybody else ever walked on is the Earth.

Will there ever be more planets?
In the words of my physics teacher 'Not in your lifetime!' Planets form from a disk of dust and gas when the star is just a proto-star. Planets cannot form after the star has been formed.
