yes, ofcalse we can travel but the thing is that we dont have a powerful rocket engines to travel so far that we can reach a planet in a year or a 2 year we take 100 of years to reach to the another planet ,so we can guess that how far they are so we have to make some powerful rocket engines ..........to reach there....it is possible for the closer planets but we cant go to the planets nearest to the sun .....and why,you know that............?
The number of planets never seen could be millions, billions, or trillions. We just have never seen them.
If there is no solar system, none of the planets will have daylight and we will never recieve the hot weather in the Summer.
Probably never. sorry
Each planet stays in it own orbit or path as it circles the sun. The orbits are very very very far apart. the planets never move out of their orbits so they never crash into each other. space probes that go from earth to Venus and Mars our closet neighbor planets have to travel for several months. space probes that go to the farther planets have to travel for years. :) Answer from my first book about space, a question and answer book.<3
Not that we know of. For all we know, the solar system could of had 99 planets but 90 blew up. Scientists are still researching all they can to do with solar explosions and if our solar system had more planets. Never know.
in our solar system the planets which are of a closer proximity to the sun than the earth never go in a retrograding motion as their orbits are smaller
Planets compared to what? We will never know.
We can never know how many planets there are in the entire universe.
No. Asteroids are basically the leftovers from the formation of the solar system. They are material that never formed a full-fledged planet.
Venus and Mercury because they are inferior planets.
They never did. In all the solar systems history, all 8 planets never alighned in a straight line
Our galaxy has over 200 billion stars; many of them do have planets, and thus qualify as a "solar system". As to the total number, we will never know, as solar systems will live and die. As a rough guess, at least 50% of all stars should have planets - so that could be classified as a "Solar System".
