Why is life not possible on all planets answer?
Living beings need the atmosphere to be of a specific composition, with oxygen to breathe and live, the atmosphere and the plants provide them with this gas The temperature of the planet matters a lot too, living beings would cease to exist if the temperature on the planet was too high or too low for them to handle
Will humans ever leave the solar system?
As respondent Charles Hornbostel explained, “With human exploration of Mars expected no earlier than the 2025-30 time frame, it is reasonable to expect humans will not have reached the orbits of Neptune and Pluto by century’s end, barring any breakthroughs in exotic propulsion technology”
How was Earth created?
When the solar system settled into its current layout about 45 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun Like its fellow terrestrial planets, Earth has a central core, a rocky mantle, and a solid crust
