Planet Solar facts

While investigating facts about Planet Solar System and Planet Solar Puerto Rico, I found out little known, but curios details like:

Scientists believe there is a 9th planet in our solar system that is roughly 10 times larger than earth. They haven't been able to locate it yet but they know it's there because of its gravitational effects on other objects.

how many planet in solar system?

The alignment of planets in our solar system that allowed us to launch Voyager spacecraft out of our solar system at the speed it went only happens once every 176 years

What is the largest planet in the solar system?

In my opinion, it is useful to put together a list of the most interesting details from trusted sources that I've come across answering what is the biggest planet in our solar system. Here are 50 of the best facts about Planet Solar System Order and Planet Solar System Song I managed to collect.

what is the hottest planet in the solar system?

1. Olympus Mons on Mars, the tallest known mountain in the solar system, is so large at its base that an observer on its peak wouldn’t know he was standing on a mountain because its slope would be obscured by the curvature of the planet itself.

2. Pluto couldn't even complete a solar orbit between being discovered and being declassified as a planet.

3. Scientists believe there is a 9th planet in our solar system that is roughly 10 times larger than earth but haven't been able to locate it yet they know it's there because of its gravitational effects on other objects.

4. An exoplanet known as J1407; a planet with a ring system so huge, it is 200x larger than Saturn's. If it took the place of Saturn in our solar system, it's rings would be brighter and more prominent than the moon in the Earth's sky.

5. Olympus Mons on Mars, the tallest known mountain in the solar system, is so large at its base that an observer on its peak wouldn’t know he was standing on a mountain because its slope would be obscured by the curvature of the planet itself.

6. We're the only planet to experience total solar eclipses. And it's entirely coincidental, because the sun just happens to be 400 times larger than the moon while also being 400 times farther away. Making them appear the same size in the sky.

7. There is a dwarf planet in our solar system that is 8 billion miles away and takes 10,000 years to complete one orbit around the Sun.

8. Triton, the largest moon of Neptune, is the only moon in our solar system with a retrograde orbit - an orbit in the opposite direction its planet, and is thus thought to be a dwarf planet that Neptune caught from the Kuiper belt.

9. NASA wants to establish a floating cloud city to study Venus. The innovative concept involves helium-filled, solar-powered airships, which could contribute to humans permanently occupying the atmosphere of the hottest planet in our solar system.

10. Humans hadn't detected any planets outside of our solar system until 1991, just 26 years ago. Before then, we had no evidence that planets existed around any other star in the universe.

Why venus is the hottest planet in the solar system?

You can easily fact check why earth is the only habitable planet in solar system by examining the linked well-known sources.

Although Mercury is closest to the sun, it is not the hottest planet in our solar system. Venus is hotter due its atmosphere trapping the heat.

The television show “Star Trek” aired 22 years before the first evidence of an exoplanet, in 1988, (planet outside our solar system) and 26 years before the first confirmed observation of exoplanet. - source

Mercury is the closest planet to Earth and to every other planet in the solar system most of the time. - source

You Could Fit All the Planets in the Solar System Between the Earth and the Moon.

NASA is creating an "interstellar internet", called Disruption Tolerant Networking (DTN). It can transmit information through solar storms, solar flares, and even past planets without losing any original data. It successfully sent images to a spacecraft located 20 million miles from earth. - source

When was the first planet discovered outside solar system?

Measure of how well a planet reflects solar energy?

There is a hypothetical undiscovered planet in our solar system, 10x bigger than Earth

Eris, discovered in 2005, is more massive than Pluto and would have qualified as the tenth planet in the solar system, until its discovery prompted the International Astronomical Union to formally define 'planet' with a size cutoff that also excluded Pluto

The ashes of Clyde Tombaugh, the man who discovered the planet Pluto, were sent to outer space on the New Horizons spacecraft making his the first human remains to leave our solar system.

Neso (moon of Neptune) is the farthest moon from its planet in the Solar System. It takes 26 Earth years to orbit Neptune planet once and it is as far away from the planet as the Earth is to Venus.

Saturn is the only planet in the solar system whose rotation time remains unknown
