How Planets Rotate (Watch it at 0.25x Speed to See 1 Hour in 1 Second)

How Planets Rotate (Slow It Down to 0.25x to See 1 Hour in 1 Second)

The rotation periods of the planets cast to a single sphere. Rotations relative to background stars.

To measure a day is to count the amount of time it takes for a planet to completely spin around and make one full rotation. This is called a sidereal day. On Earth, a sidereal day is almost exactly 23 hours and 56 minutes.

We know how long an Earth day is, but how about the other planets in our solar system? How long does it take for those planets to spin one full rotation? And what is the best way to show the answer to this question?

The simple answer is:

Mercury: 58d 16h, 10.83 km/h
Venus: 243d 26m, 6.52 km/h
Earth: 23h 56m, 1574 km/h
Mars: 24h 36m, 866 km/h
Jupiter: 9h 55m, 45,583 km/h
Saturn: 10h 33m, 36,840 km/h
Uranus: 17h 14m, 14,794 km/h
Neptune: 16h, 9,719 km/h


In this dataset, it's possible to see all 8 planets on the sphere rotating at once and we have set Earth's ~24 hour day/rotation to happen in 60 seconds. Next to each planet's name, we have listed the time it takes for each planet to make one full rotation as well as the speed each planet moves at its equator. Jupiter, for example, makes one rotation in 9h 55m but moves 27 times faster than Earth at its equator, spinning at a whopping 45,583 km/h!

We have included two PIPs (picture in pictures) that can be toggled on for further explanation related to this concept. A PIP of the approximate sizes of the planets relative to each other and a PIP illustrating that if you viewed all the planets from the same point and at an angular diameter of 30 degrees - about ten feet from the sphere - each planet would appear to have a similar size.

We all know that Earth is a planet that is a habitable planet for living beings. There are about eight planets in our solar system and the Earth is the only planet where human life exists. Scientists are researching other planets like Jupiter, Mars, Venus, etc. if they can also be habitable planets. Watch this video to understand if there is any other planet better than earth for life.

The guys at the Stan Winston Studio are having some fun with an unused helmet & head that Digital Domain requested for Ron Howard's Apollo 13. The creators decided not to use it because it was too gory.

Планета Суперземля может стать нашим новым домом
Планета Суперземля может стать нашим новым домом Teacherflix 3 Views • 2 years ago

Некоторые вопросы о космосе остаются актуальными всегда: "Есть ли жизнь за пределами планеты Земля?", "Есть ли во Вселенной планеты, похожие на Землю?" На данный момент экзопланета Kepler-1649c является самой похожей на нашу планетой. Разве этот факт не вселяет надежды, что она может стать нашим новым домом?

На самом деле в космосе полным-полно сюрпризов и необычных небесных тел. Например, есть планеты, где всегда царит ночь, а есть такие, где идет дождь из стекла, и планеты с алмазным ядром. Ух ты! Хотел бы я слетать на такую планету!

All about Asia for Kids | Learn all about the amazing continent of Asia Teacherflix 3 Views • 2 years ago

Have you ever heard of Taj Mahal or the Great Wall of China? Or perhaps you know something about Mount Everest or Mount Fuji. All of these amazing places are found in a country in Asia! In All about Asia for Kids, you will learn some really cool facts about this amazing continent. For instance, the first dinosaur eggs ever discovered were discovered in the Gobi Desert. In addition, both the highest and lowest points in the world are found in Asia.

Asia is an incredibly diverse continent in many ways. Because it is so big—it takes up about 30% of the earth's land!—it includes eight different climate types! It is also diverse in its cultures, religions, and plant and animal life. You will find panda bears in the alpine and mountain regions, but you will also find Asian elephants, polar bears, and Komodo dragons in other parts.

Asia is home to the two most-populated countries in the world: China and India. In fact, there are 1.4 billion people living in China, and India is home to 1.3 billion people! Some really interesting landmarks in Asia include the Great Wall of China, the Forbidden City, the Dotonbori District, and The Great Buddha of Kamakura. There are so many more wonderful things to learn about this incredible continent!

We hope you and your student(s) enjoyed learning about the wonderful continent of Asia! If you want even more information, head over to our website and download one of our many free lesson plans, full of activities, worksheets, and more!

A boiling water reactor uses 235U, enriched as uranium dioxide, as its fuel. The fuel is assembled into rods housed in a steel vessel that is submerged in water. The nuclear fission causes the water to boil, generating steam.

In a nuclear power reactor, the energy released is used as heat to make steam to generate electricity. (In a research reactor the main purpose is to utilise the actual neutrons produced in the core. In most naval reactors, steam drives a turbine directly for propulsion.)
