Mars is bigger than Pluto and smaller than Uranus, so try to lose some weight.

this is what i be responsive to off the appropriate of my head -It takes 248 Earth years for it to pass around the solar -A Pluto day is approximately 6 days -It probable has an atmosphere made quite often of methane. the ambience freezes and falls to its floor while it that's furthest from the solar. -It has one important moon, Charon. Charon is a few million/2 the dimensions of Pluto and provides the comparable face to Pluto (purely like our moon). Pluto has 2 different moons, i be responsive to one is termed Nix yet can no longer remember the different one. -Pluto has a loopy eccentric orbit it incredibly is approximately 17 stages out of the airplane of something of the photograph voltaic gadget. This incorporates it periodically interior the orbit of Neptune. So Pluto turns into closer to the solar than Neptune for about two decades (The final time it got here approximately grew to become into between 1977 and 1999) -Pluto grew to become into got here across in 1930 by making use of Clyde Tombaugh (sp) He used a blink comparator to make his discovery For extra, you're able to to attempt Wikipedia or google.

MARS
-------------
Mars Quick Facts
General
One of five planets known to ancients; Mars was Roman god of war, agriculture and the state
Yellowish brown to reddish color; occasionally the third brightest object in the night sky after the Moon and Venus
Physical Characteristics
Average diameter 6,780 kilometers (4,212 miles); about half the size of Earth, but twice the size of Earth's Moon
Same land area as Earth, reminiscent of a rocky desert
Mass 1/10th of Earth's; gravity only 38 percent as strong as Earth's
Density 3.9 times greater than water (compared to Earth's 5.5 times greater than water)
No planet-wide magnetic field detected; only localized ancient remnant fields in various regions
Orbit
Fourth planet from the Sun, the next beyond Earth
About 1.5 times farther from the Sun than Earth is
Orbit elliptical; distance from Sun varies from a minimum of 206.7 million kilometers (128.4 mil-lions miles) to a maximum of 249.2 million kilometers (154.8 million miles); average distance from the Sun 227.7 million kilometers (141.5 million miles)
Revolves around Sun once every 687 Earth days
Rotation period (length of day) 24 hours, 39 min, 35 sec (1.027 Earth days)
Poles tilted 25 degrees, creating seasons similar to Earth's
Environment
Atmosphere composed chiefly of carbon dioxide (95.3%), nitrogen (2.7%) and argon (1.6%)
Surface atmospheric pressure less than 1/100th that of Earth's average
Surface winds up to 80 miles per hour (40 meters per second)
Local, regional and global dust storms; also whirlwinds called dust devils
Surface temperature averages -53 C (-64 F); varies from -128 C (-199 F) during polar night to 27 C (80 F) at equator during midday at closest point in orbit to Sun
Features
Highest point is Olympus Mons, a huge shield volcano about 26 kilometers (16 miles) high and 600 kilometers (370 miles) across; has about the same area as Arizona
Canyon system of Valles Marineris is largest and deepest known in solar system; extends more than 4,000 kilometers (2,500 miles) and has 5 to 10 kilometers (3 to 6 miles) relief from floors to tops of surrounding plateaus
"Canals" observed by Giovanni Schiaparelli and Percival Lowell about 100 years ago were a visual illusion in which dark areas appeared connected by lines. The Mariner 9 and Viking missions of the 1970s, however, established that Mars has channels possibly cut by ancient rivers
Moons
Two irregularly shaped moons, each only a few kilometers wide
Larger moon named Phobos ("fear"); smaller is Deimos ("terror"), named for attributes personi-fied in Greek mythology as sons of the god of war.
Uranus
----------
Position: Seventh from Sun
Distance from Sun: 2,870,990,000 km
Uranus Day: .72 Earth Days
Uranus Year: 84.01 Earth Years
Orbital Speed: 6.6 km/sec
Eccentricity of Orbit: 0.047
Satellites: 15 (plus rings)
Diameter: 51,800 km
Mass: 8.686e25 kg
Major Atmospheric Gas: Hydrogen
Uranus is the third largest planet in the Solar System.
The atmosphere of Uranus is composed of hydrogen, helium, and methane. The methane in the atmosphere absorbs red light, giving the planet a blue-green color.
Uranus is considered unusual because the planet is tipped on its side. The poles actually point towards the Sun. This is due to the fact that its magnetic field is tilted 60 degrees from the axis of rotation.
Like Venus, Uranus spins from east to west, which is opposite from the spin of Earth.
Uranus has rings that are composed of fine dust, rocks, and ice boulders. The rings are very faint and remained undiscovered until the Voyager 2 spacecraft visited the planet in 1986.
Voyager 2 is the only spacecraft to have visited Uranus.
Uranus is named after the Greek god of the sky. Uranus was the husband of Gaia, the goddess of the Earth.
PLUTO
----------
Position: Ninth from Sun
Distance from Sun: 5,913,520,000 km (39.5 AU)
Plutonian Day: 6.39 Earth Days
Plutonian Year: 247.7 Earth Years
Orbital Speed: 4.74 km/sec
Eccentricity of Orbit: 0.2482
Satellites: 1
Diameter: 2340 km
Mass: 1.32e22 kg
Major Atmospheric Gas: Methane
Puto is the smallest planet in our Solar System.
Pluto is named after the Greek lord of the underworld, Hades. It's only satellite, Charon, is named after the boatman who ferried the dead across the River Styx to Hades.
