The bigger the telescope, the deeper it can see into space. The first telescopes could not see all of the planets, but as the technology (and interest to fund it) grew, telescope size increased, and we were able to see deeper and deeper into space.
All the objects that orbit the Sun lie roughly in the same plane. Satellites that are sent out to transmit data back to Earth will often visit many of the planets, since the satellite itself is set on a trajectory parallel to said plane. Satellites offered us additional information about Pluto--and will continue to explore even further--but the "evidence" of Pluto was seen through a telescope.
What else can I help you with?
Where the scientists live in Pluto planet?
No one lives in or on Pluto. No one has visited Pluto.
What Pluto observations did not help convince scientists to change Pluto's status from that of a planet?
Observations of Pluto's orbit and size did not provide enough evidence to change its status from a planet. Astronomers cited factors such as its small size and irregular orbit as reasons for excluding it from the planetary classification.
Why do scientists say Pluto is usually the ninth planet?
No scientists say that. Scientists know that Pluto is a dwarf planet, and not one of the 8 major planets of our solar system.
What evidence prompted scientists to conclude that Pluto has two additional moons?
Scientists discovered two additional moons around Pluto, named Nix and Hydra, using images captured by the Hubble Space Telescope in 2005. Analysis of these images showed two faint objects near Pluto that were later confirmed to be its moons. This discovery provided further insight into Pluto's complex satellite system.
What problems must scientists overcome to make such a visit to Pluto?
The problem is that Pluto is to far, it takes a to long, and there is nothing there at Pluto.
What is Pluto's designation?
A dwarf planet, although that designation continues to be disputed by some scientists.
What planet do scientists know little about?
Pluto
Are there any active volcanoes on Pluto?
Pluto is geologically active but there is no evidence of volcanoes.
Does Pluto have evidence of volcanic eruption?
no
What planet is still a mystery to scientists?
no Pluto is fully studied and there are no mysteries but there are planets beyond Pluto
Are there landslides on Pluto?
This is not known. Scientists don't know very much of what the surface of Pluto is like.
What planet do scientists NOT consider a major planet?
the only planet that scientists do not consider a planet is Pluto, (but they also found new planets in the asteroid belt.)Pluto
