They were just dragging their feet once the definition of a planet was solidified. A planet is now considered a nonluminous object, larder than an asteroid or comet, that orbits a star. Whether they were waiting on a comparison of Pluto vs. asteroid measurements...I do not know.

∙ 14y agoIt took a very long time to discover the planet Pluto mainly as it is a small one and it is also the last planet of the nine from the sun, and a very powerful telescope was needed to discover it.

∙ 15y agoIt is an issue of both distance and politics. Pluto is extrodinarily distant, 49 times farther from the sun than the distance between the earth and the sun at its farthest point, making such exploration very difficult and expensive. This expense makes any decision to begin an exploration program very politically unpopular, as it is felt that such large funding costs could be better served in other programs. That being said, there is a NASA robotic probe currently under way to Pluto called the New Horizons mission. Launched in 2006, and traveling at a speed of 58,000 Km/h (incidentally the highest earth-relative speed ever achieved by a space probe), it will arrive in the Kuiper Belt (The area of the solar system where Pluto is located) in 2015.

∙ 13y ago- It is tiny, smaller than earth's moon.
- It is the furthest away object ever considered a planet.
- It has a very strange orbit for a planet, more like the orbit of a comet.

∙ 12y agoBecause until we had stronger telescopes we could not see Pluto because of its distance from the sun.
Wiki User
∙ 12y agoBecause it is farther away.
its tiny and Jupiter would be covering it
Wiki User
∙ 12y ago- It's small
- It's a long way away
- It is very faint

What is strange about Pluto's moon?
Pluto is a double planet system. Its moon Charon is so big compared in size that it doesn't orbit Pluto. Instead they spin around each other, so, if you are on the surface of Pluto, Charon will always remain in the sky! Note: Pluto has 3 moons other than Charon. They are called Nix, Hydra and P4 (which was identified by the Hubble Space Telescope in 2011).
What is the percipitation on Pluto?
No there is no precipitation on Pluto because the freezing cold temperatures any gases or water would be frozen but maybe long ago there was water on Pluto but it has been frozen as Pluto's surface so Pluto is surface layer is ice
How long would it take a rocket to travel from Pluto to the sun?
On January 19, 2006 a space probe was launched and sent to Pluto. It was expected to reach Pluto in 2015. So it would take about 9 years to get to Pluto.
Pluto how many time needed to rotate on its axis?
Pluto rotates much more slowly than Earth so a day on Pluto is much longer than a day on Earth. A day on Pluto is 6.4 Earth days or 153.3 hours long.
What is unusual about Pluto's moon?
Pluto's moon is about the size of Pluto, so they pretty much orbit each other.
Why does pluto take so long to orbit the earth?
No answer Pluto orbits the Sun Pluto does not orbit the Earth
How long is it on Pluto?
veary long Pluto is not a planet so u no ok that's all i can say
How likely is it that Pluto may have other undiscovered moons?
Quiet unlikely. The size of Pluto is quite small, so if it had another moon, it would be very visible and not likely to be missed, unless it was smaller than we could notice, in which case it would not be classified as a moon.
Why does it take Pluto so long to go around the sun?
Becaus it is so far away from the sun, it has a bigger orbit, so it takes Pluto a long time to travel around the sun

DoPluto dwell on the inner edge of the oort cloud?
The Oort cloud is a long way past Pluto, so Pluto is much nearer to us and the Sun.

Pluto rotates much more slowly than Earth so a day on Pluto is much longer than a day on Earth. A day on Pluto is 6.4 Earth days or 153.3 hours long.
Why does it take so long to find out if Pluto has life?
Because it takes many years to reach Pluto (with a probe), and then, many more years to transmit information back.
Why are the galapagos islands so famous?
it has many undiscovered animals
How long it takes to obrit the Pluto?
It takes pluto 248 years to orbit the sun but sometimes it depends on neptune because they swap places so if pluto was in neptune place it would then take 220 years or something like that.
