The solar system consists of the Sun and objects that orbit it, including 8 planets and over 200 moons. The planets from closest to farthest from the Sun are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Mercury is the smallest planet and has no atmosphere or geological activity. Venus has the densest atmosphere of any terrestrial planet. Earth is the only planet known to harbor life due to its abundance of liquid water. Mars has a reddish surface due to iron oxide dust. Jupiter is the largest planet and over twice as massive as all other planets combined. Saturn has rings and is less dense than Earth. Uranus and Neptune are icy giants on the outer edges of

2. What is the solar system?
The Solar System is the gravitationally bound system of the
Sun and the objects that orbit it. olar system, assemblage
consisting of the Sun—an average star in the Milky Way
Galaxy—and those bodies orbiting around it: 8 (formerly 9)
planets with more than 210 known planetary satellites
(moons); many asteroids, some with their own satellites;
comets and other icy bodies; and vast reaches of highly
tenuous gas ..

3. This are the diferent planets in the solar
system.

4. Mercury is the first planet from
the Sun and the smallest in the
Solar System. It is a terrestrial
planet with a heavily cratered
surface due to overlapping
impact events. These features
are well preserved since the
planet has no geological activity
and an extremely tenuous
atmosphere called an exosphere.
Distance from the sun:8 million km
Orbital period: 88 days
Length of day: 59d 0h 0m
Radius: 2,439.7 km
Gravity: 3.7 m/s²
Mass: 3.285 × 10^23 kg (0.055 M⊕)
Surface area: 74.8 million km²

5. Venus is the second planet
from the Sun. It is a rocky
planet with the densest
atmosphere of all the rocky
bodies in the Solar System, and
the only one with a mass and
size that is close to that of its
orbital neighbour Earth.
Orbital period: 225 days
Distance from Sun: 108.2 million km
Length of day: 243d 0h 0m
Radius: 6,051.8 km
Gravity: 8.87 m/s²
Surface area: 460.2 million km²
Mass: 4.867 × 10^24 kg (0.815 M⊕)

6. Earth is the third planet from
the Sun and the only
astronomical object known to
harbor life. This is enabled by
Earth being a water world, the
only one in the Solar System
sustaining liquid surface water.
Almost all of Earth's water is
contained in its global ocean,
covering 70.8% of Earth's
surface.
Age: 4.543 billion years
Distance from Sun: 149.6 million km
Gravity: 9.807 m/s²
Mass: 5.972 × 10^24 kg
Surface area: 510.1 million km²
Population: 7.888 billion (2021)

7. Mars is the fourth planet and
the furthest terrestrial planet
from the Sun. The reddish color
of its surface is due to finely
grained iron(III) oxide dust in
the soil, giving it the nickname
"the Red Planet". Mars's radius
is second smallest among the
planets in the Solar System at
3,389.5 km.
Gravity: 3.71 m/s²
Distance from Sun: 227.9 million km
Orbital period: 687 days
Length of day: 1d 0h 37m
Radius: 3,389.5 km
Coordinates: RA 13h 51m 4s | Dec -11° 8′ 35″

8. Saturn is the sixth planet from the Sun and the
second-largest in the Solar System, after
Jupiter. It is a gas giant with an average radius
of about nine-and-a-half times that of Earth. It
has only one-eighth the average density of
Earth, but is over 95 times more massive.
Jupiter is the fifth planet from the Sun and the
largest in the Solar System. It is a gas giant with a
mass more than two and a half times that of all the
other planets in the Solar System combined, and
slightly less than one one-thousandth the mass of
the Sun.

9. Neptune is the eighth planet from the Sun
and the farthest IAU-recognized planet in the
Solar System. It is the fourth-largest planet in
the Solar System by diameter, the third-most-
massive planet, and the densest giant planet.
It is 17 times the mass of Earth, and slightly
more massive than its near-twin Uranus.
Uranus is the seventh planet from the Sun
and is a gaseous cyan ice giant. Most of the
planet is made of water, ammonia, and
methane in a supercritical phase of matter,
which in astronomy is called 'ice' or volatiles.
