Our Place In Space- The Solar System

Earth is the only planet known to support life because it has the right conditions for life to exist. It has a suitable atmosphere, moderate temperatures, and liquid water, which are essential for the development and sustenance of life forms. Other planets in our solar system, such as Mars or Venus, do not have these favorable conditions. Additionally, no other planet outside our solar system has been discovered to have the necessary conditions for life as we know it. Therefore, Earth stands as the only known planet where life can thrive.

The sun is warmer than Mercury because the sun is a massive ball of hot gases that emits heat and light, while Mercury is a planet that receives heat from the sun. The sun's temperature can reach millions of degrees, making it much hotter than Mercury.

The statement "The moon goes around the Earth" is true because the moon orbits around the Earth in a path called an orbit. This orbit is elliptical in shape, with the Earth located at one of the foci of the ellipse. The moon's orbit takes approximately 27.3 days to complete, resulting in different phases of the moon as it moves in relation to the Earth and the Sun. This phenomenon is known as lunar motion and has been observed and studied for centuries.

The statement is incorrect. Mars is not known as the Blue Planet. In fact, Earth is often referred to as the Blue Planet because it appears blue when seen from space due to the abundance of water on its surface. Mars, on the other hand, is known as the Red Planet because of its reddish appearance caused by iron oxide (rust) on its surface.

The statement "The Earth goes around the sun" is true because the Earth orbits the sun in a circular path called an orbit. This is known as the heliocentric model of the solar system, where the sun is at the center and the planets, including Earth, revolve around it. The Earth takes approximately 365.25 days to complete one orbit around the sun, resulting in the cycle of seasons and the length of a year.

Jupiter is indeed the largest planet in our solar system. It has a diameter of about 86,881 miles, which is more than 11 times the diameter of Earth. It is also more than twice as massive as all the other planets combined. Its large size is due to its composition, mainly consisting of hydrogen and helium gases. Jupiter's immense size and gravity have a significant impact on the solar system, influencing the orbits of other planets and asteroids.

Saturn has more moons than Earth. This is because Saturn is a gas giant planet and has a larger mass and gravitational pull compared to Earth. This allows Saturn to capture and retain more moons in its orbit. As of now, Saturn has over 80 known moons, while Earth only has one natural satellite, the Moon. Therefore, the statement is true.

Venus is not the closest planet to the sun. The closest planet to the sun is Mercury. Venus is the second planet from the sun.

Jupiter has a fast rotation speed, completing one rotation on its axis in about 10 hours. This means that a day on Jupiter is shorter than a day on Earth, which lasts for approximately 24 hours. Therefore, the statement that a day on Jupiter lasts for only 10 hours is true.
