Mercury's magnetic field is weaker than Earth's because its core had cooled and solidified more quickly than Earth's. Although Mercury's magnetic field is much weaker than Earth's magnetic field, it is still strong enough to deflect the solar wind, inducing a magnetosphere. must. A second Earth-sized world is found in habitable zone of a star with three previously known planets. It is mysterious why TRAPPIST-1e has a much rockier composition than the rest of the planets. iii Vast distances to Earth's closest neighbours. "The Earth as the Largest of the Four Terrestrial Planets." The sixth planet from the Sun, and the second-largest in the Solar System after Jupiter, is Saturn. The sizes are listed in units of Jupiter radii (71,492km). For reference (1 gm/cm3 = 1000 kg/m3). Bouncing radio waves off the planet from satellites and the Earth. Six of these small satellites will work together to create the largest radio telescope ever launched. Residual They are also known as gas dwarfs. Space and Terrestrial Robotic Exploration Laboratory, University of Arizona . Its a gas giant with a radius about nine times that of Earth. Mercury is also a dense planet, composed mostly of iron and nickel with an iron core. The Giant Planets The two largest planets, Jupiter and Saturn, have nearly the same chemical makeup as the Sun; they are composed primarily of the two elements hydrogen and helium, with 75% of their mass being hydrogen and 25% helium. A load of lumber of weight $W=25 \mathrm{kN}$ is being raised by a mobile crane. It is mostly made up of nitrogen (N2), with traces of methane (CH4) and carbon monoxide (CO), both of which are liberated from ice on Plutos surface by being vaporized. The biggest canyon on Venus stretches across the surface for 4,000 miles (nearly 6,500 kilometers). Mars is the fourth planet from the Sun and the last terrestrial planet of the solar system.
