Is there an undiscovered planet in our solar system?
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.
What was the last planet to be explored?
Pluto
Pluto was the last planet discovered, although that distinction returned to Neptune when Pluto was reclassified as a dwarf planet. Pluto was discovered in 1930 by the astronomer Clyde Tombaugh. Many people had been searching for a ninth planet – the elusive planet X – for quite a while.

Is this the closest habitable planet found outside our Solar System?
Image credit: ESO/B. Tafreshi UNSW Australia astronomers have discovered the closest potentially habitable planet found outside our solar system so far, orbiting a star just 14 light-years away. The planet, more than four times the mass of the Earth, is one of three that the team detected around a red dwarf star called Wolf 1061.
Is there a planet without a sun?
Or perhaps this planet formed in an entirely different and unknown way. Scientists don’t know for sure! This is an exciting find. It is the first really good evidence that planets without suns actually exist. It’s also exciting because this planet is very young.
How many planets are in the Solar System in real time?
Real-Time, Interactive Solar System. There are more planets than stars in our galaxy. The current count orbiting our star: eight. The inner, rocky planets are Mercury, Venus, Earth and Mars. NASA’s newest rover — Perseverance — landed on Mars on Feb. 18, 2021.
Are there any undiscovered terrestrial planets in the Solar System?
The region you need to focus on is the area between the Kuiper belt and the Oort cloud. It’s certainly possible that there are undiscovered terrestrial planet sized objects out there. There are almost certainly many dwarf planets in the outskirts of our Solar System.
