Stars and planets took a long time to form due to the complex processes involved in the coalescence of matter in the universe. After the Big Bang, it took hundreds of millions of years for matter to cool and clump together, allowing hydrogen and helium to form the first stars. These stars then produced heavier elements through nuclear fusion, which were released into space when they exploded as supernovae. This enriched the surrounding gas and dust, providing the necessary materials for the formation of planets, a process that unfolded over billions of years.
The outer planets take longer.
If you are talking about Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune, these planets all orbit the Sun.It wasn't very long ago that these were the only planets we knew about. But with the development of enormously powerful space telescopes and newer more powerful computers, scientists have now discovered over 300 "extra-solar planets"; planets that orbit other stars. We've discovered so many, so quickly, than we now need to revise our theories on how planets form. We used to think that planets would be rare; now, it looks like a majority of mid-sized stars will have planets.
The slowest stars to form are typically the lowest-mass stars, often referred to as red dwarfs. These stars form in dense molecular clouds and take a long time—often millions to tens of millions of years—to accumulate enough mass for nuclear fusion to begin. Their formation is characterized by a gradual buildup of material, leading to a longer and more extended process compared to more massive stars, which can ignite their nuclear processes relatively quickly.
The object that floats above Earth to take pictures of planets and stars is a space telescope. Examples include the Hubble Space Telescope, which orbits the Earth, and the James Webb Space Telescope, which will be positioned at a Lagrange point in space. These telescopes are designed to capture high-quality images and data from space.
Stars and planets make up a very small fraction of the universe's total volume. The vast majority of space in the universe is empty, consisting of hydrogen and helium gas, dark matter, and dark energy. Stars and planets are concentrated in galaxies, which themselves make up a small portion of the universe.
That depends on which solar system and planet you are asking about - we now know for planets orbiting other stars.
its called a satellite, a large object floats in space above earth to take pictures of stars and planets
To see planets, stars, comets and to take pictures.
782,347,445,192,660,812,003,422,683 cubic feet.
What do you mean by how long would it take? Like how long would it take to orbit around the sun?
The outer planets take longer.
Very long.

i did this research and made my own equation on my own, take our Galaxy for example 1 galaxy=150-350 billion stars lets take 250 billion stars, and if each star has a solar system of 1 to 9 planets, lets say each star has 5. 5 planets times 250 billion stars = 1,250 billion planets and if at least 1 in 5 planets has life on it 1/5 X 1,250 billion planets = 250 billion planets so i think maybe at least 250 billion planets in OUR galaxy have life but that's only our Galaxy (Milky Way) and in the universe there are billions of galaxies maybe trillions, and how do we know this is the only universe, could there be more?
Stars are constantly in movement.
