If Earth & Mars were the same distance from the Sun & about 4 months apart on their orbit, would we to see Mars as a planet or just a brighter star?
How would it look like in our sky if Mars was orbiting our Sun on the exact same orbital track as our Earth but it was about 4 months ahead of us?
How is the orbit of Mars around the Sun determined? Realistically, what year will we land a human on Mars? When will we be able to travel to Mars? Does the sun rise in the East on Mars? What is a good estimation for the year when a human will land on Mars? How many years will it take from the Earth to reach Mars? Can you seen the Moon on Mars? How will we tell time on Mars? Will we go by Mars’ rotation of the sun, or continue using Earth's time? How would life on Mars be like? When can we expect humans to go to Mars? When can human possibly go and land on Mars? With current technology, how long would it take to reach Mars from Earth? How close are the planets of our solar system to being in the same orbital plane? What would happen if we moved the earth closer to the sun? How far is Mars from Earth? How far is Mars away from Earth? How many days, weeks, months, or years would it take to get there? Would a year on Earth be shorter if our planet was orbiting two suns? How is the atmosphere of Mars different from that of Earth? If the Sun disappeared, would the Earth continue in its orbit for 8½ minutes? How long does it take for a signal from Earth to reach Mars? Is it possible for a star to orbit a planet?  Has it ever been observed? How long would the Earth follow its orbit around the Sun if the Sun were to disappear? It there a moon in Mars? If sun suddenly disappeared then we will know after 8 minutes but in what time earth will go in straight line? If the life on Mars exist since beginning like earth, would us go there for vacation? When will people be able to live on Mars? Will it be possible for us to actually travel to Mars by 2025? How big would the sun look on other planets? How do we detect life on Mars? Does a planetary orbit depend on the sun?
