Pluto was automatically disqualified because its highly elliptical orbit overlaps with that of Neptune and so it could only be classed as a dwarf planet. Pluto’s status had been contested for many years. It is further away and considerably smaller than the eight other “traditional” planets in the Solar System.

Pluto (minor planet designation: 134340 Pluto) is a dwarf planet in the Kuiper belt, a ring of bodies beyond the orbit of Neptune. This led the International Astronomical Union (IAU) in 2006 to formally define the term “planet” — excluding Pluto and reclassifying it as a dwarf planet.

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. Pluto was found to be smaller and less massive than all the other planets.

Answer: No. From 1979 to 1999, Pluto was the eighth planet from the sun. In 1999, it slipped beyond Neptune to become the ninth. But Pluto’s 248-year orbit around the sun takes it 17 degrees above and below the plane in which Neptune and the other planets travel.

1) Pluto could collide with Neptune, destroying Pluto and having some very dramatic effects on Neptune. 2) Pluto could be thrown off in some random direction, either out of the solar system entirely or towards the inner solar system where it would encounter the other planets.

Its orbit is also more oval-shaped, or elliptical, than those of the planets. That means that sometimes Pluto is a lot nearer to the Sun than at other times, At times Pluto’s orbit brings it closer to the Sun than Neptune.

Pluto is currently the most distant planet from the Sun, though as you probably know Pluto was “demoted” to dwarf planet status in August 2006.

Neptune

The idea of a second sun in our solar system is not as bizarre as it might sound. Binary star systems (two stars orbiting the same center of mass) are quite common. In fact, Alpha Centauri, our solar system’s nearest neighbor, is a binary system.

The moment when Venus passes behind the Sun is typically around seven months after reaching greatest prominence in the morning sky. It does not return to the evening sky until around a year after its disappearance from the morning sky.

Q 7) In which part of the sky can you find Venus if it is visible as an evening star? Solution 7: Venus appears either in the eastern sky before sunrise or in the western sky after sunset. When it appears after sunset in the western sky, it is called an evening star.
