What would planet 9 be called?
The alleged “Planet Nine,” also called “Planet X,” is believed to be about 10 times the mass of Earth and 5,000 times the mass of Pluto.
What is up with planet 9?
Planet Nine is a hypothetical planet in the outer region of the Solar System. Its gravitational effects could explain the peculiar clustering of orbits for a group of extreme trans-Neptunian objects (ETNOs), bodies beyond Neptune that orbit the Sun at distances averaging more than 250 times that of the Earth.
Does planet 9 have moons?
Planet Nine search finds 12 new Jovian moons.
Is there a super-Earth?
What is a super-Earth? Super-Earths – a class of planets unlike any in our solar system – are more massive than Earth yet lighter than ice giants like Neptune and Uranus, and can be made of gas, rock or a combination of both. They are between twice the size of Earth and up to 10 times its mass.
Who invented 9 planets?
Five planets have been known since ancient times — Mercury, Venus, Mars, Jupiter, and Saturn. The first new planet discovered was Uranus. It was discovered by the English astronomer Sir William Herschel in 1781….
| PLANET | DIST. FROM SUN (A.U.) | ORBIT PERIOD (EARTH-YEARS) |
|---|---|---|
| Neptune | 30.11 | 164.79 |
| Pluto | 39.44 | 248.5 |
Who Discovered Planet 9?
Rowan-Robinson recently went digging into 38-year-old data and claims he has found the hypothetical Planet Nine.
How much does Planet Nine weigh?
From their calculations taken from Kuiper Belt Objects, the scientists came up with approximate figures for Planet Nine. They estimate Planet Nine to be about 6.2 Earth masses, with an orbit that takes it from 300 astronomical units ( AU, with 1 AU being the distance from Earth to the sun) out to 380 AU from the sun.
What would happen if an asteroid hit the earth’s surface?
The oceans cover about 75\% of the Earth’s surface, so it is likely the asteroid will hit an ocean. The amount of water in the ocean is nowhere near large enough to “cushion” the asteroid. The asteroid will push the water aside and hit the ocean floor to create a large crater. The water pushed aside will form a huge tidal wave, a tsunami.
How long would it take to reach Planet Nine?
Brown thinks that if Planet Nine is confirmed to exist, a probe could reach it in as little as 20 years by using a powered slingshot trajectory around the Sun. The planet is estimated to have 5 to 10 times the mass of Earth and a radius of 2 to 4 times Earth’s.
What is Planet Nine’s orbit around the Sun?
Planet Nine is hypothesized to follow an elliptical orbit around the Sun with an eccentricity of 0.2 to 0.5. The planet’s semi-major axis is estimated to be 400 AU to 800 AU, roughly 13 to 26 times the distance from Neptune to the Sun. It would take the planet between 10,000 and 20,000 years to make one full orbit around the Sun.
