- Saturn is not the only planet with rings. Jupiter, Uranus, and Neptune also have rings, although they are much fainter and less spectacular than Saturn’s.
- Scientists believe that Saturn is approximately -350° F (-212° C).
- Saturn is 74,898 miles (120,537 km.) wide, nearly 10 times wider than Earth. Approximately 750 Earths could fit inside of Saturn.
- The first spacecraft to fly by Saturn was Pioneer 11, which blasted off in 1973 and arrived at Saturn in 1979. Voyagers 1 and 2 also completed fly-bys in 1980 and 1981. Voyager 1 is now the farthest human-made object in space.
- Nearly 1,600 Saturns could fit inside the Sun.
- A year on Earth is 365.256 days. A year on Saturn is 10,759.22 days.
- On July 1, 2004, the Cassini-Huygens was the first spacecraft to orbit Saturn.
- Launched on October 15, 1997
- It traveled over 2,000,000,000 miles at a speed of 70,700 miles per hour before it reached the ringed planet.
- A day on Earth is 24 hours. A day on Saturn is 10 hours 39 minutes.
- Winds in Saturn’s atmosphere travel up to 1,100 miles (1,800 km.) per hour, much faster than those on Jupiter.
- Storms on Saturn can last for months or even years.
- A long-lived 2004 storm on Saturn, named the “Dragon Storm,” created mega-lightning 1,000 times more powerful than lightning on Earth.
- In early 2010, amateur astronomers spotted a massive ammonia blizzard raging on Saturn.
- The monster storm is five times larger than “Snowmageddon,” the snowstorm that shut down Washington D.C. in February 2010.
- The Assyrians, who lived in modern-day Iraq, were the first to record sighting Saturn in 700 B.C.
- They called the planet the Star of Ninib, after the Assyrian sun god of spring.
- In astrology, Saturn is the opposite of Jupiter.
- As the seventh day of the week, Saturday is named after Saturn, the farthest of the seven objects in the solar system known in ancient times.
- Discovered in 1789 by William Herschel, Saturn’s moon Enceladus has geysers that erupt icy particles, water vapor, and organic compounds. It is the shiniest object in the solar system because its icy surface reflects most of the light it receives.
- The surface gravity on Mars is only about 38% of the surface gravity on Earth, so if you weigh 100 pounds on Earth, you would weigh only 38 pounds on Mars.
- Mars is the second smallest planet in the solar system after mercury.
- And it is the fourth planet from the sun
- “SUNSETS ON MARS ARE BLUE.”
- Mars is being explored for over four decades now because it is considered as a favorable place for human existence.
- Mars is also referred to as the “Red Planet” because it has a high content of iron oxide which makes it appear reddish.
- Mars has a thin atmosphere.
- Mars has only two moons as compared to Uranus’ twenty-seven.
- They are named: Phobos and Deimos.
- These moons are small and are irregularly shaped.
- The maximum pressure of Mar’s core is expected to be 400,000 times the pressure of Earth’s atmosphere at sea level.
- The density of Mars is 100 times less dense than Earth.
- Mars has low atmospheric pressure on its surface
- Mars takes twice the time Earth takes to complete a full revolution around the sun.
- The orbit of Mars and Earth are also not on the same plane. There is a tilt of a few degrees between the orbits of the two neighboring planets.
- “OLYMPUS MONS — THE TALLEST MOUNTAIN IN THE SOLAR SYSTEM — IS ON MARS.”
- Photographed by the Hubble Space Telescope in 2003, the red planet 11 hours before its closest approach to Earth in 60,000 years. Image credit – NASA
- Mars has sufficient ice on its polar regions
- Solar Conjunction is the term used to describe the coming of Sun between the Earth and Mars.
- Ancient Babylonians named the Moon, Mars, Mercury, Venus, Jupiter, and Saturn.
- Venus is the second brightest natural object in the sky.
- Venus is sometimes referred to as the “morning star” and “evening star”.
- One day on Venus is longer than one year
- Venus has no rings
- Venus is sometimes called Earth’s sister planet.
- Venus has no moons.
- Billions of years ago, the climate of Venus may be similar to that of Earth
- Venus rotates in the opposite direction to other planets.
- Venus is the hottest planet in the solar system with an average surface temperature of 462°C (863°F).
- The temperature on Venus doesn’t vary much between the night and day.
- The estimated age of the Venusian surface is around 300-400 million years old.
- The atmospheric pressure of Venus is 92 times stronger than Earth’s.
- Venus has a very weak magnetic field.
- Venus is the only planet in the Solar System to be named after a female figure.
- Venus orbits the sun in an ellipse, but its orbit is the closest to being a circle out of all the planets
- Venus is the closest planet to Earth.
- Pressure on Venus is 90 times greater than the pressure at sea level.
- One day is longer than a year
- Venus has more than 1800 volcanoes on its surface
- Venus has winds up to 450 miles per hour
- International Space Station goes about 17,210 mph (27,700km)
- International Space Station is longer than a football field
- The station masses around 450 tons (400 metric tons)
- orbiting about 250 miles (400-km) above us and is one of the most expensive project.
- Its assembly required dozens and dozens of launches by Russia and the US including 37 space shuttle flights.
- The ISS has taken 13 years and as much as $150 billion to build and fly to call it valuable real estate is an understatement.
- International Space Station living space is 13,702 cu.ft. (338 cu. m.)
- International Space Station was launched in 1998 by Russia.
- The ISS crews have eaten about 25,000 meals since 2000. That’s a staggering “seven tons of supplies per three astronauts for six months.”That’s 32,558 Big Macs.
- Astronauts on the International Space Station see 16 more sunrises and sunsets each day.
- That’s because the station travels at about 17,500 miles per hour, completing a full orbit of Earth every 90 minutes (1 hour 30 minutes).
- On the space station, there was a part of Asia where we would always see the pollution.
- While astronauts don’t need to sit down in order to relax and watch a movie floating in place would work just as well they tend to do it anyway.
- The first module launched was back on Nov. 20, 1998, at 1:40 am.
- The ISS travels an equivalent distance to the Moon and back in about a day.
- The ISS has 32,333 cubic feet of pressurized volume and weighs 930,000 pounds.
- The U.S. solar panel surface area is 38,400 square feet (.88 acre) – large enough to cover eight basketball courts (94 ft x 50 ft x 8 = 37,600 sq ft).
- The International Space Station can be seen from Earth with your eye and is the largest artificial satellite that has ever orbited Earth.
- It took an astounding 136 space flights on seven different types of launch vehicles to build it.
- It flies at 4.791 miles per second (7.71 km/s).
- It weighs almost 1 million pounds including visiting spacecraft.
