....Well to beging with, we live on one. Other then that they just remain a mystery in Science that our scientists have explored but can continue to do so for quite some time and still learn new things.
They influenced us today by naming some of the planets and some other things we used today
The alignment of planets in our solar system constantly changes as they orbit the Sun at different speeds and inclinations. Today, the planets are not significantly aligned in a straight line in the sky. However, certain planets may be clustered closer together depending on their positions in their orbits.
As of today no, but maybe in the future.
it is because of the natral resources
Planets that used to be planets but aren't any more. Example: Pluto
yes about 2,000,000,000 the thing that made thes planets was the "Big Bang". that's why we are alive today.
It was Johannes Kepler who produced the theory of the planets' positions and speeds which is accepted today.
It's probably they used to somehow study the planets. Already they supposedly "knew" that the other planets evolved around Earth, so then it would have been easier for them to know that the planets lined up every 26 000 years.
Planets
Not by the scientific community, but his extensive data was used by Keppler to figure out that planets had eliptical orbits. this led to kepplers laws of planetary motion.
he used his telescope to map all of the planets.
