Is there a 10th planet in our solar system?
In February 2016, its distance from the Sun was 96.3 astronomical units (1.441×1010 km; 8.95×109 mi), roughly three times that of Pluto.
Because Eris appeared to be larger than Pluto, NASA initially described it as the Solar System’s tenth planet..
What are the 15 planets?
What is the new 9th planet?
Planet Nine is a theoretical, undiscovered giant planet in the mysterious far reaches of our solar system. The presence of Planet Nine has been hypothesized to explain everything from the tilt of the sun’s spin axis to the apparent clustering in the orbits of small, icy asteroids beyond Neptune.
Which planet has most volcanoes?
Io is one of the four large moons of Jupiter, the largest planet. It is the most volcanically active world in the solar system. It is almost literally covered with active volcanoes.
How cold is Eris?
It has a highly eccentric orbit around the Sun, which causes its surface temperature to vary from -217 degrees Celsius to -243 degrees Celsius. Observations of Eris have led scientists to believe that it has frozen methane on its surface. At 2400 kilometers in diameter, Eris is slightly larger than Pluto.
What is the tenth planet called?
Artist’s rendering of Eris, announced in July 2005 by Mike Brown of Caltech. It is more massive than Pluto.
What is the hottest planet?
VenusVenus is the exception, as its proximity to the Sun and dense atmosphere make it our solar system’s hottest planet.
Why is Pluto not part of our solar system?
Answer. The International Astronomical Union (IAU) downgraded the status of Pluto to that of a dwarf planet because it did not meet the three criteria the IAU uses to define a full-sized planet. Essentially Pluto meets all the criteria except one—it “has not cleared its neighboring region of other objects.”
Where is Eris located?
Eris is the furthest dwarf planet from the Sun, and is also the most massive currently recognized dwarf planet. Eris is located beyond the orbit of Neptune and beyond the Kuiper belt in a region known as the “scattered disc”.

What is the most unique planet?
Uranus the unique. Saturn may be flashy and pretty, and Jupiter may be huge and dramatic, but they can’t hold a candle to Uranus’s intrigue. While all the other planets spin like tops around the sun, Uranus lies on its side.
Is Pluto a planet in 2020?
According to the International Astronomical Union, the organization charged with naming all celestial bodies and deciding on their statuses, Pluto is still not an official planet in our solar system.
What is the rarest planet?
Known as GW Orionis (or GW Ori) and located about 1,300 light-years from Earth, the system is a rare example of a triple-star solar system, with two suns orbiting one another at the center, and a third star swirling around its siblings from several hundred million miles away.
What is the biggest dwarf planet?
ErisEris is one of the largest known dwarf planets in our solar system. It’s about the same size as Pluto, but is three times farther from the Sun. Eris first appeared to be larger than Pluto.
What are the 12 planets?
If the resolution is approved, the 12 planets in our solar system listed in order of their proximity to the sun would be Mercury, Venus, Earth, Mars, Ceres, Jupiter, Saturn, Uranus, Neptune, Pluto, Charon, and the provisionally named 2003 UB313.
What is the least known planet?
Scientists have found the smallest known planet — smaller than Mercury, the smallest planet in Earth’s solar system. A team of scientists including two Yale University astronomers has discovered the smallest planet yet detected.
What planet is just like Earth?
Kepler-452bKepler-452b (a planet sometimes quoted to be an Earth 2.0 or Earth’s Cousin based on its characteristics; also known by its Kepler Object of Interest designation KOI-7016.01) is an exoplanet orbiting the Sun-like star Kepler-452 about 1,402 light-years (430 pc) from Earth in the constellation Cygnus.
What is the most dangerous planet?
Venus450. 0.015% 0.007% 3.5% 64% Page 2 Venus is the most dangerous planet in the solar system: its surface is at 393°C, hot enough to melt lead. It’s even hotter than the planet Mercury, which is closest to the Sun. Venus’ atmosphere is acidic and thick.
