The main reason is that Pluto is much farther away. Mars is close enough that even from an orbit around Earth we can get decent images of it while we can only get vague pictures of Pluto. We have also been able to sent several probes to Mars that have made detailed maps from orbit and have taken samples of its surface and atmosphere. So far we have launched one probe to Pluto, but it hasn't gotten there yet.

Why do scientists know less about Pluto than about any other planet?
Pluto is difficult to observe astronomically, because it is both very far away, and relatively small, so people can't get information.
How many times larger is Earth than Pluto?
its not, Pluto is much smaller than the earth. By volume, Pluto is less than 0.6% of Earths volume.
What planets have 3 moons or less?
the earth Pluto and that's all i know
Why do you think that scientists discuss manned missions to mars but not to venus?
Scientists discuss manned missions to Mars because it would be much easier to send humans to Mars because the conditions on Mars are much less extreme than those on Venus. For example, surface temperatures on Mars range between -125ºC to 35ºC while those on Venus range between 450ºC to 475ºC.
What is the similarities and differences of the planet mars and Pluto?
Similarities• Both celestial objects are located in our Solar System and orbit around the Sun in relatively elliptical orbits compared to the planets.• Until August 2006, both Mars and Pluto were considered planets by mankind.• Both celestial objects are terrestrial, which means they have a rocky surface.• Both celestial objects are close to some kind of belt in our Solar System (Mars is close to the asteroid belt; Pluto is close to the Kuiper Belt).• Both celestial objects have atmospheres composed primarily of CO2 (carbon dioxide).• Both celestial objects' temperatures reach well below zero in both Fahrenheit and Celsius degrees.• Both celestial objects have moons.• Both celestial objects have a tilt and thus both have seasons.Differences• Mars is a planet; Pluto is a dwarf planet.• Mars is located in the inner Solar System; Pluto is located in the outer Solar System.• They are different in mass, density, and gravitational pull.• They are different in their relative distances from the Sun.• They are different in their rotational and orbital periods.• Both are different in the amount of moons they have (Mars has 2; Pluto has 5).• Mars has been studied by many unmanned missions, but to date, Pluto hasn't been visited by an unmanned mission, and this will stay that way until 2015, when the spacecraft New Horizonsarrives at Pluto.• Mars and Pluto's seasons have different lengths (on Mars, a season is less than one Earth year long; on Pluto, a season is at least 50 Earth years long.
Mars and Pluto have just about the same mass which planet has greater gravity and why?
Actually, the idea that Pluto had about the same mass as Mars is outdated. It is now known that Pluto has less than 2% the mass of Mars, and therefore has less gravity.

What planets have less than 15 known satellites?
Mercury, Venus, Earth, Mars, Neptune and Pluto.

If a student weighs 100 pounds on earth how much more or less would she weigh on Pluto then mars?
because he was an scarydy crow

Does venus have a weaker or stronger gravity?
There is less oxygen on Pluto of all planets because it is a lot smallerno, it is lesserweakerPluto has a weaker pull than that of and planet, even Mercury!Pluto's gravitational pull is much less than that of Earth due to their difference in size.No. Pluto has a much less mass than earthLess. The force of gravity is proportional to the mass of the planet and the object, but, relative to the same object, the force of gravity on Pluto is much less than on Earth, because Pluto is much less massive than Earth. According to Wikipedia, the acceleration due to gravity on Pluto is 0.067g or 6.7% of gravity on Earth.
