What is the new 9 planet?
The talk of Planet Nine first emerged in January 2015 when a duo of astronomers from the California Institute for Technology (Caltech) suggested that a Neptune-sized planet orbits our Sun in a highly elongated orbit that lies far beyond Pluto.
What is the new planet we found?
The Kepler space telescope identified the exoplanet, and its discovery was announced by NASA on 23 July 2015. The planet is about 1,800 light-years (550 pc) away from the Solar System….Kepler-452b.

TOI-2109b is a kind of “hot Jupiter,” which is a gas giant that orbits close to its parent star. Thus far, astronomers have identified about 400 of these planets.
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. But does Planet Nine actually exist?
What planet is least known in your solar system?
now designated a dwarf planet (but retains its asteroid label), along with Pluto, which was discovered in 1930; Eris, found in 2003; Haumea, found in 2004; and Makemake, found in 2005. There may be hundreds of dwarf planets in Pluto’s realm. Our solar system formed about 4.6 billion years ago. The four
Are there still undiscovered planets in the Solar System?
Yes, there are likely undiscovered planets in our solar system. This is possible because of very recent changes in technology and also in growing understanding of the definition of a planet. The definition of a planet must take into account the size of the planet, the behavior of the planet in gravitational terms, and the relation of that planet to other planets and to the sun.
What are the names of the newly discovered planets?
Two new “super Earths” – planets larger than Earth but smaller than Neptune, about which little is known – were discovered using a machine-learning algorithm. Details: The new planets are called K2-293b and K2-294b. The first is about 2.5 times as big around as Earth, the second about 1.7 times.
