Why are probes used to gather information about other planets?
Space probes have helped scientists get information about our solar system. The information they gather is used to help us understand the weather and other changes which happen on planets other than the Earth. This information is important in helping to plan other space missions such as ones to Mars and to Saturn.
Why do we need to study about solar system?
Knowledge about the solar system is more important than ever. It helps us appreciate the Earth. NASA says studying the solar system may help us understand important issues, such as how global warming will affect the Earth or how life originated on our planet.
How do scientists gather information about the planets?
Well, we can send spacecraft to the planets. Man-made robots have landed on the moon, venus and mars and studied their surface. In almost every case, whether it is an instrument actually on the planet, or a telescope looking up from the earth, scientists use some variation of an instrument called a spectrometer.
Why is it important for children to learn about planets?
Learning about the solar system can allow everyone, especially your children, to gain a greater appreciation for the frailness of Earth. Knowing why your planet is extra special and how you can protect that uniqueness helps keep the planet safe and healthy for their generation to live in.
How do we explore other planets?
- Scientists use powerful telescopes—on Earth and in space—to study distant stars and galaxies.
- Five robotic spacecraft have sufficient velocity to escape the bounds of our solar system and travel into interstellar space, but only one—NASA’s Voyager 1—has crossed that boundary so far.
Why do we explore planets around other stars?
More than nebulae, galaxies or even other stars, planets around other stars readily fit into our shared cultural understanding of the universe. Exoplanet exploration bridges the heavens into human consciousness, and that’s why we do it.” Mary Voytek, senior scientist and director of NASA’s Astrobiology Program:
How do scientists search for habitable planets?
In the Zone: How Scientists Search for Habitable Planets. For example, the Super Earth planet called Kepler-62f, discovered by Kepler to orbit in the middle of a habitable zone around a cool star, orbits closer to its star than Earth. The planet takes just 267 days to complete an orbit, as compared to 365 days for Earth.
How do people relate to the idea of a planet?
“People in many cultures can relate to the idea of a planet: They live on one, in Earth’s Moon they directly see another world, and from a young age they learn the names of the other planets in our solar system.
Why do you like to discover exoplanets?
In particular I like discovering exoplanets because the planets in our solar system are so substantial and tangible to us that I can then imagine what exoplanets around other stars might look like.” Matthew W. Smith, systems engineer, NASA’s Jet Propulsion Laboratory:
