Terrestrial planets or Earth-like planets are Mercury, Venus, Earth and Mars. They all have a solid surface and their sizes are relatively small. The following table shows their general properties.

Terrestrial planet: Earth-like planet - another term for a rocky planet.
Titan: Moon of Saturn
Triton: Neptune's moon. It has a retrograde orbit (orbits in the opposite direction to Neptune's rotation).
A terrestrial planet ejected from the solar system by a primordial encounter with or another large planet.
A terrestrial planet with a thin atmosphere, Mars has surface features reminiscent both of the impact craters of the Moon and the volcanoes, valleys, deserts and polar ice caps of Earth.
A terrestrial planet orbiting 51 Pegasi at around the center of the calculated habitable zone would have an average orbital distance of about 1.6 AU, just beyond the orbit of Mars (towards the Main Asteroid Belt) in the Solar System.
The terrestrial planets formed at about the same time, in the same general region of space and experienced similar forces and processes during their development.
The terrestrial planets have distances from the Sun in the AU range: the semimajor axis of Mercury is 0.39 AU, that of Venus is 0.72 AU, and that of Mars is 1.52 AU. Once we turn to the giant planets, we jump to a length scale of tens of AU.
The terrestrial planets are the four innermost planets in the solar system, Mercury, Venus, Earth and Mars. They are called terrestrial because they have a compact, rocky surface like the Earth's.
The terrestrial planets are composed primarily of rock and metal and have relatively high densities, slow rotation, solid surfaces, no rings and few satellites.

Earth is a terrestrial planet, meaning that it is a rocky body, rather than a gas giant like Jupiter. It is the largest of the four solar terrestrial planets in size and mass.

Super-earths are terrestrial planets with a mass somewhere between that of our own planet and icy giants like Uranus. From the size and period of its transit, astronomers deduced that GJ 1214b is 34,441.7 kilometres across, which is 2.
The farthest of the terrestrial planets from the Sun, Mars orbits between Earth and the asteroid belt.
It is not only the second-largest satellite among the planets, but it also has the second-densest atmosphere of all the terrestrial planets and satellites, barring only Venus.
Plains, or relatively flat or smoothly undulating surfaces, are ubiquitous on Mercury and the other terrestrial planets. They represent a canvas on which other landforms develop.
Earth is the third planet, third terrestrial planet, and of course our home. Earth is about 4.6 billion years old with a complex and ever changing history and life cycle that intrigues most if not all scientists.
Though these objects only become visible in the atmosphere they are extra-terrestrial planetary bodies, and properly belong to the domain of astronomy.
In contrast to the gas giant planets there are the terrestrial planets in the inner part of the solar system, consisting of Mercury, Venus, Earth (and the Moon), and Mars. The terrestrial planets are characterized by higher densities (5.
Jupiter has features very different from terrestrial planets. Its composition is more like that of stars, and if it has any solid surface it is hidden deep at its center: Jupiter is apparently almost entirely gas and liquid.
The Earth is unique amongst the terrestrial planets in having a large satellite, the Moon, which, relative to the Earth, has the largest mass of any satellite - parent system.
55 Cancri consists of a yellow dwarf and a smaller red dwarf, with five planets orbiting the primary star; one terrestrial planet and four gas giants. It is the only planetary system discovered to have five planets and possibly more.
The interior of Earth, like that of the other terrestrial planets, is chemically divided into an outer siliceous solid crust, a highly viscous mantle, an outer core that is less viscous than the mantle, and an inner core.
Until recently, Mercury was the least explored of the terrestrial planets, visited only by Mariner 10 in the 1970s. In March 2011, the MESSENGER spacecraft goes into orbit around Mercury.

That means that the terrestrial planets makeup the inner Solar System and Jupiter, Saturn, Uranus, and Neptune make up the outer.
The inner four are sometimes called the terrestrial planets; and the term giant planets denotes those planets from Jupiter to Neptune. Between these groups is a belt of numerous, very small bodies called asteroids, or sometimes the minor planets.
basalt has a low viscosity (resistance to flow.) Basalt is composed primarily of plagioclase feldspar and pyroxene; other minerals such as olivine and ilmenite are usually present. Basalt is the most common volcanic rock on the terrestrial planets.
The giant impact theory emerged from this conference with nearly consensus support by scientists, enhanced by new models of planet formation that suggested large impacts were actually quite common events in the late stages of terrestrial planet ...
