Venus is the second closest planet to the Sun. A day on Venus is longer than a year. It takes Venus longer to rotate once on its axis than to complete one orbit of the Sun. That’s 243 Earth days to rotate once – the longest rotation of any planet in the Solar System – and only 224.7 Earth days to complete an orbit of the Sun.

Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System, larger than only Mercury. Mars is named for the Roman god of war. Mars is a terrestrial planet with a thin atmosphere (less than 1% of Earth's) and has a crust primarily composed of elements similar to Earth's crust, as well as a core made of iron and nickel. Mars has surface features such as impact craters, valleys, dunes, and polar ice caps. Mars is often called the Red Planet.

Earth is the third planet from the Sun and the only astronomical object known to harbor life. It is about eight light minutes away from the Sun and orbits it, taking a year (about 365.25 days) to complete one revolution. Earth's axis of rotation is tilted with respect to the perpendicular to its orbital plane around the Sun, producing seasons.

The smallest planet in our solar system and nearest to the Sun, Mercury is only slightly larger than Earth's Moon. From the surface of Mercury, the Sun would appear more than three times as large as it does when viewed from Earth, and the sunlight would be as much as seven times brighter. Despite its proximity to the Sun, Mercury is not the hottest planet in our solar system – that title belongs to nearby Venus, thanks to its dense atmosphere. Because of Mercury's elliptical – egg-shaped – orbit, and sluggish rotation, the Sun appears to rise briefly, set, and rise again from some parts of the planet's surface. The same thing happens in reverse at sunset.

One of the nicknames of Venus is Evening Star. It’s also known as the Morning Star. Of course, Venus isn’t a star at all, but a planet. The orbit of Venus is inside the orbit of Earth. Unlike the outer planets, Venus is always relatively close to the Sun in the sky. When Venus is on one side of the Sun, it’s trailing the Sun in the sky and brightens into view shortly after the Sun sets, when the sky is dark enough for it to be visible. When Venus is at its brightest, it becomes visible just minutes after the Sun goes down. This is when Venus is seen as the Evening Star. When Venus is on the other side of the Sun, it leads the Sun as it travels across the sky. Venus will rise in the morning a few hours before the Sun. Then as the Sun rises, the sky brightens and Venus fades away in the daytime sky. This is Venus the Morning Star.

Moons – also called natural satellites – come in many shapes, sizes, and types. They are generally solid bodies, and few have atmospheres. Of the terrestrial (rocky) planets of the Solar System, Mercury and Venus have no moons at all, Earth has one, and Mars has two small moons. In the outer solar system, the gas giants Jupiter and Saturn and the ice giants Uranus and Neptune have dozens of moons.

None of the Solar System planets can compete with Venus when it comes to temperature. Venus is the hottest planet in our solar system, with a surface temperature of 869 degrees Fahrenheit, or 465 degrees Celsius. Despite being farther from the Sun than Mercury, Venus is hotter than Mercury because its carbon dioxide and sulfuric acid-filled atmosphere causes a greenhouse effect, which traps heat. However, Venus is not the hottest planet in the known universe. The hottest known planet is KELT-9b, which has a surface temperature of 7,800 degrees Fahrenheit, or 4,300 degrees Celsius, and it is 670 light-years from Earth.

Venus is one of the 5 planets visible with the unaided eye. This means that ancient people knew of Venus, and tracked its movements in the sky. Venus was named after the Roman Goddess of Love and Beauty (in Greek, Aphrodite). In ancient times, Venus was known to the Babylonians as Ishtar, the goddess of womanhood and love, so the planet has a long-standing tradition of being associated with amore. Furthermore, the symbol for the planet Venus is the symbol for womanhood; a circle with a cross on the bottom.

Mercury is the smallest planet in the Solar System and the closest to the Sun. Its orbit around the Sun takes 87.97 Earth days, the shortest of all the Sun's planets. Having almost no atmosphere to retain heat, it has surface temperatures that vary diurnally more than on any other planet in the Solar System, ranging from −280 °F at night to 800 °F during the day across the equatorial regions. The polar regions are constantly below −136 °F.

Olympus Mons (Latin for Mount Olympus) is a large shield volcano on Mars. The volcano has a height of over 21.9 km (13.6 mi or 72,000 ft) as measured by the Mars Orbiter Laser Altimeter (MOLA). Olympus Mons is about two and a half times Mount Everest's height above sea level. It is the largest and highest known mountain and volcano in the Solar System, in competition only with Tamu Massif. It is associated with the Tharsis Montes, a large volcanic region on Mars.

Roman mythology is to thank for the monikers of most of the eight planets in the solar system. But the Earth, the planet that’s currently home to an estimated 7.3 billion people, is the only one in the Solar System whose name doesn't come from Roman or Greek mythology, but rather from Old English and Germanic words. The meaning is “ground.”

NASA's Mars Exploration Rover (MER) mission was a robotic space mission involving two Mars rovers, Spirit and Opportunity, exploring the planet Mars. It began in 2003 with the launch of the two rovers to explore the Martian surface and geology; both landed on Mars at separate locations in January 2004. Both rovers far outlived their planned missions of 90 Martian solar days: MER-A Spirit was active until March 22, 2010, while MER-B Opportunity was active until June 10, 2018.

Jupiter, Saturn, Uranus, and Neptune are known as the Jovian (Jupiter-like) planets because they are all gigantic compared with Earth and have a gaseous nature like Jupiter's. The Jovian planets are referred to as the "gas giants." On the other hand, the planets Mercury, Venus, Earth, and Mars are not "gas giants." Instead, they are called terrestrial planets because they have a compact, rocky surface like Earth's. The terrestrial planets are the four innermost planets in the solar system.

It will collide with Mars eventually. The Martian moon Phobos orbits only a few thousand miles above the Red Planet's surface. Its proximity to its planet is one of the reasons astronomers were unable to see the satellite until the late 19th century. In fact, the moon is getting closer to Mars over the centuries and eventually will either break up or be pulled into the Martian surface.

From the surface of Mercury, the Sun would appear more than three times as large as it does when viewed from Earth, and the sunlight would be as much as seven times brighter. Mercury's highly eccentric, egg-shaped orbit takes the planet as close as 29 million miles and as far as 43 million miles from the Sun. It speeds around the Sun every 88 days, traveling through space at nearly 29 miles per second, faster than any other planet.

The Sun is a 4.5 billion-year-old yellow dwarf star – a hot glowing ball of hydrogen and helium – at the center of our solar system. It’s about 93 million miles from Earth. Without the Sun’s energy, life as we know it could not exist on our home planet. Our Sun is a star with a radius of about 435,000 miles. Many stars are much larger – but the Sun is far more massive than our home planet: it would take more than 330,000 Earths to match the mass of the Sun, and it would take 1.3 million Earths to fill the Sun’s volume.

The proper term for the surface material of Mars is regolith, which is a broad term for the loose material that covers the surface of some planets (Earth, Mars, Mercury) and Earth’s moon. Soil is a type of regolith that, by definition, includes organic matter. Since there is no organic matter on Mars, there is technically no soil. However, for practical matters, scientists commonly refer to Martian “soil” despite this technical difference.

Theia is a hypothesized ancient planet in the early Solar System that, according to the giant-impact hypothesis, collided with the early Earth around 4.5 billion years ago, with some of the resulting ejected debris gathering to form the Moon. Theia could explain why Earth's core is larger than expected for a body its size, with Theia's core and mantle fusing with those of Earth. Theia is hypothesized to have been about the size of Mars. Theia may have formed in the outer Solar System and provided much of Earth's water.
