Spins in opposite direction to the other terrestrial planets. •. Volcano-covered surface; most craters erased by volcanic activity. •. Dense CO2 atmosphere causing greenhouse effect on planet. •. Hot enough to melt lead; clouds of sulphuric acid. •. Atmospheric Pressure is x 92 that of Earth. •. Can be seen from Earth as bright
reflecting sunlight. Together, the Sun and all the objects that orbit it make up the Solar. System. The Solar System is the Sun's system. The Earth is the third planet from the Sun. It has a smaller companion going around it, called the Moon. Most planets have at least one moon of their own, and the giant planets have dozens.
The Solar System. The sun (a star). The planets. Asteroids. Kuiper Belt Objects. Comets. Dust (zodiacal light). Interackons: Gravity causes planets to orbit around the sun. Heat created via fusion in the sun heats the planets. Occasionally, objects in the solar system can collide
lution of the Solar System with the Sun, the planets, moons and comets, and last but not least of the Earth, including its environment and near-Earth space. All of this has been brought about during the first fifty years of the space age. For the last decade, the International Space Science Institute (ISSI) has participated.
5 Nov 2011 This article relates two topics of central importance in modern astronomy – the discov- ery some fifteen years ago of the first planets around other stars (exoplanets), and the centuries-old problem of understanding the origin of our own solar system, with its plan- ets, planetary satellites, asteroids, and comets

This graphic of the solar system was made using real images of the planets and comet Hale-Bopp. It is not to scale! To show a scale model of the solar system with the Sun being 1cm would require about 64 meters of paper! Image credit: Maggie Mosetti, NASA. This book was produced to commemorate the Year of the Solar
The sun is the center of our solar system. It is the largest body in our solar system. Nine planets follow paths called orbits around the sun. The shape of each orbit is called an ellipse. An ellipse is a flattened circle (see the picture at the bottom of page 3). The nine planets are Mercury, Venus,. Earth, Mars, Jupiter, Saturn,
Among otherwise welleducated people, it is common to hear the terms Solar. System, Galaxy, and Universe interchanged. For instance, you might hear "Jupiter is the biggest planet in the Galaxy," or the question, "How many stars are there in our solar system?" These may seem silly to those who know a bit about the subject
supported the concept of a “solar system" in which all the plan- ets, including Earth, revolve around a central star — the Sun. Planetary moons, the rings of Saturn, and more planets were eventually discovered: Uranus (in 1781) and Neptune (1846). The largest known asteroid, Ceres, was discovered between Mars.
