Are there any planets we don’t know about?

Are there any planets we don’t know about?

There are different categories of “planet” such as a major planet (Earth/Jupiter), dwarf planet (Pluto/Ceres), and minor planet (asteroids/comets). So, technically speaking, there are plenty of undiscovered planets out there since there are still loads of undiscovered asteroids and comets.

What is the most unknown planet?

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.

What is the 14 planet?

Noting the similarities in composition and size between Mercury and what would become Earth’s Moon, Farazea suggested that the future moon, the fourteenth planet in the solar system by what might have been ancient Mondasian reckoning, originally formed as a twin planet to Mercury before being dislodged from its orbit, …

What’s beyond the universe?

The trite answer is that both space and time were created at the big bang about 14 billion years ago, so there is nothing beyond the universe. However, much of the universe exists beyond the observable universe, which is maybe about 90 billion light years across.

Is the space infinite?

There’s a limit to how much of the universe we can see. The observable universe is finite in that it hasn’t existed forever. It extends 46 billion light years in every direction from us. (While our universe is 13.8 billion years old, the observable universe reaches further since the universe is expanding).

Is Planet 9 a black hole?

A group of astronomers, including Avi Loeb at Harvard University, suggested Planet Nine may be a tiny black hole somewhere out in the Oort Cloud. If Planet Nine turns out to be Black Hole Nine instead, it’s probably about the size of a grapefruit but about 5 to 10 times the mass of Earth.

What’s the rarest thing in space?

Only 1-in-10,000 galaxies fall into the rarest category of all: ring galaxies. With a dense core consisting of old stars, and a circular or elliptical ring consisting of bright, blue, young stars, the first ring was only discovered in 1950: Hoag’s object.

What is the 11th planet called?

Pluto

What is diamond planet?

NASA has taken a closer look at 55 Cancri e, an exoplanet that earned the nickname “diamond planet” due to research that suggests it has a carbon-rich composition. Even if we could reach these diamond exoplanets, they wouldn’t be appealing places to visit.

What planet rains diamonds?

On Saturn it occasionally rains diamonds.

What is the pink planet called?

Named GJ 504b, the planet is made of pink gas. It’s similar to Jupiter, a giant gas planet in our own solar system. But GJ 504b is four times more massive. At 460°F, it’s the temperature of a hot oven, and it’s the planet’s intense heat that causes it to glow.

What planet has only 88 days?

Mercury takes 59 Earth days to make one full rotation. But a year on Mercury goes fast. Because it’s the closest planet to the sun, it goes around the Sun in just 88 Earth days.

What is the darkest planet?

Consequently, HD 149026b might be the blackest known planet in the Universe, in addition to the hottest. The temperature of this dark and balmy planet was taken with NASA’s Spitzer Space Telescope. While the planet reflects no visible light, its heat causes it to radiate a little visible and a lot of infrared light.

Are there 19 planets?

Pluto isn’t the only dwarf planet orbiting the Sun; there are others as well. The dwarf planets Ceres, Haumea, Makemake, and Eris, are also orbiting our Sun, so there are actually 13 planets in our Solar System.

How many planets are still undiscovered?

At least two as-yet undiscovered planets as big as Earth or larger may be hiding in the outer fringes of the solar system, scientists believe. The secret worlds are thought to exist beyond the orbits of Neptune, the furthest true planet from the Sun, and the even more distant tiny “dwarf planet” Pluto.

Is there an unseen planet in our solar system?

In the outer Solar System, well beyond the orbit of Neptune and Pluto, a ninth planet may be waiting to be discovered. This ‘ghost planet’, nicknamed Planet 9 or Planet X, has never been observed directly, but peculiar goings-on in the space beyond Neptune hint tantalisingly at its existence.

How many unknown planets are there?

The first confirmation of detection occurred in 1992. A different planet, initially detected in 1988, was confirmed in 2003. As of 1 December 2022, there are 5,284 confirmed exoplanets in 3,899 planetary systems, with 847 systems having more than one planet.

What planets have not been explored?

Publications such as the New York Times have called Pluto “the last of known worlds to be explored” and “the end of an era of planetary exploration.”
