Mars once had flowing rivers and lakes.

Scientists have discovered evidence suggesting that Mars had a warmer and wetter past. Channels, valleys, and rocks formed by ancient water flows indicate that the red planet was once home to flowing rivers, lakes, and even oceans.

Neptune emits more heat than it receives from the Sun.

Neptune, the eighth planet from the Sun, emits more heat energy than it receives from the Sun. This phenomenon is due to the internal heat generated by the planet’s gravitational contraction and the residual heat from its formation.

The Moon is Earth’s only natural satellite.

Known simply as “The Moon,” Earth’s natural satellite is the fifth-largest moon in the entire solar system. It plays a vital role in stabilizing Earth’s axial tilt and provides us with the beautiful phenomenon of lunar phases.

Saturn’s moon Enceladus has liquid water beneath its icy surface.

Enceladus, one of Saturn’s moons, has captured the attention of scientists due to its subsurface ocean of liquid water. This hidden ocean, coupled with active geysers erupting from its icy surface, makes Enceladus a promising candidate for the existence of life beyond Earth.

Jupiter’s moon Europa has a global ocean beneath its icy crust.

Europa, one of Jupiter’s moons, is believed to harbor a global ocean beneath its icy crust. This ocean, kept liquid by tidal heating, makes Europa one of the most intriguing places in the solar system to search for life.

Pluto was reclassified as a “dwarf planet” in 2006.

Once considered the ninth planet in our solar system, Pluto was reclassified as a “dwarf planet” by the International Astronomical Union in This reclassification sparked a debate about the definition of a planet.

The largest volcano in our solar system is on Earth’s ocean floor.

Mauna Loa, located in Hawaii, is the largest volcano on Earth but holds the title for the largest volcano in the entire solar system when measured from its base on the ocean floor.

Venus has the hottest surface temperature of any planet in the solar system.

Venus, with its thick atmosphere, experiences an extreme greenhouse effect. This causes its surface temperature to reach a scorching 900 degrees Fahrenheit (475 degrees Celsius), making it the hottest planet in the solar system.

The Sun makes up 99.86% of the total mass of our solar system.

The Sun is the dominating figure in our solar system, accounting for over 99% of its total mass. The remaining mass is distributed among all the planets, moons, asteroids, and other celestial bodies.

Mars has the tallest volcano and deepest canyon in the solar system.

In addition to being home to Olympus Mons, the tallest volcano, Mars also boasts Valles Marineris, the largest canyon. This massive rift extends for about 2,500 miles (4,000 kilometers) and reaches depths of up to 7 miles (11 kilometers).

The largest storm in the solar system occurs on Saturn.

The storm known as the “Great White Spot” occurs on Saturn approximately once every 30 Earth years. This enormous storm system can span thousands of kilometers and lasts several months, covering a significant portion of the planet’s surface.

Planetary scientists use various spacecraft and telescopes to study the planets and their moons.

To unravel the mysteries of the planets and their moons, planetary scientists rely on a wide array of spacecraft and telescopes. Through missions such as Voyager, Cassini, and Hubble, we have been able to gather invaluable data and images, deepening our understanding of the vast universe we call home.
