The dwarf planet Pluto is smaller than Mercury. Earth is the largest terrestrial or inner planet. Our solar system comprises eight planets, which fall into two categories: the smaller, rocky inner planets (Mercury, Venus, Earth, and Mars) and the larger, gas giants (Jupiter, Saturn, Uranus, and Neptune).

How small can a planet be and still have Earth-like gravity?

A planet made from denser material than Earth might have equal gravity to Earth but a smaller radius. How small can a planet be and still have Earth gravity? Ideally it should be habitable by humans, so not made of anything dangerous, radioactive or unstable.

Out of the remaining six, two of the biggest moons in the Solar System belong to Saturn, the second biggest

How Many Planets are in our Solar System? | Facts & Amount

A star that hosts planets orbiting around it is called a planetary system, or a stellar system, if more than two stars are present. Our planetary system is called the Solar System, referencing the name of our Sun, and it hosts eight planets.. The eight planets in our Solar System, in order from the Sun, are the four terrestrial planets Mercury, Venus, Earth,

Earth-size planets common in galaxy

Last year, astronomers were excited to discover that the number of exoplanets increases toward smaller sizes, suggesting that there are many Earth-size planets in the galaxy. A new analysis of three years of Kepler data shows that this increase plateaus around twice Earth size. Nevertheless, Earth-like planets occur around at least 17 percent of sun-like stars.

Observations from Earth have revealed that Pluto''s brightness varies with a period of 6.3873 Earth days, which is now well established as its rotation period (sidereal day).Of the planets, only Mercury, with a rotation period of almost 59 days, and Venus, with 243 days, turn more slowly.Pluto''s axis of rotation is tilted at an angle of 120° from the perpendicular to the

Stirred, not shaken: How pebbles become planets

Using a new process in planetary formation modeling, where planets grow from tiny bodies called "pebbles," Southwest Research Institute scientists can explain why Mars is so much smaller than Earth. This same process also explains the rapid formation of the gas giants Jupiter and Saturn, as reported earlier this year.
