ExoplanetsExoplanets are planets that orbit stars outside our solar system. Scientists have discovered thousands of these planets using telescopes and space missions. Some exoplanets resemble Earth, while others are gas giants or frozen worlds. Studying exoplanets helps scientists understand how planets form and whether any might support life.Science and Engineering Practices (SEP): Developing and Using ModelsScientists use models to figure out how exoplanets move around their stars, how their...

Inner vs outer planetsThe solar system is divided into inner and outer planets, each with unique characteristics. The inner planets, Mercury, Venus, Earth, and Mars, are small, rocky, and located closer to the Sun. In contrast, the outer planets, Jupiter, Saturn, Uranus, and Neptune, are much larger, composed mostly of gas or ice, and positioned farther from the Sun. By understanding the differences between inner and outer planets, scientists can learn more about planetary formation, space...

MarsMars, often called the "Red Planet," is the fourth planet from the Sun and the most Earth-like planet in our solar system. Its reddish color comes from iron oxide, or rust, that coats its surface. Mars is home to the largest volcano in the solar system, Olympus Mons, and deep valleys such as Valles Marineris. Scientists study the planet to understand its history, search for signs of water, and explore the potential for future human missions. Scientists can better predict how planetary...

Shuttles And Space StationsA space shuttle is a reusable spacecraft that transports astronauts, satellites, and cargo between Earth and space. NASA's Space Shuttle Program, which operated from 1981 to 2011, enabled astronauts to conduct experiments, repair satellites, and construct the International Space Station (ISS). A space station is a large structure that orbits Earth, providing a long-term habitat where astronauts live and conduct research. The ISS is the largest space station, involving...

The gravitational acceleration of an object near the Earth's surface is called the acceleration due to gravity. It can be measured by conducting simple experiments on Earth. However, such an experiment is impossible to conduct on the surface of other planets.
Astronomical observations are thus used to measure the acceleration due to gravity on other planets. This can be determined by observing the effect of a planet's gravity on objects close to it. The crucial factor that helps in this...

AsteroidsAsteroids are rocky objects that orbit the Sun. They are much smaller than planets and are primarily found in the asteroid belt, a region between Mars and Jupiter. Scientists believe asteroids are leftover fragments from the early solar system that never formed into planets. Some asteroids are tiny, while others span hundreds of miles in diameter. As they move through space, they occasionally collide with one another, breaking into smaller pieces. Sometimes, an asteroid may pass close...
