Planet neptune is the eight and farthless known planet from the sun in the solar system. This planet is the fourth largest planet by its diameter in the solar system. It is the third most densest gaint planet and massive planet. planet neptune is the 17 times the mass of the planet earth, and it is little bigger or slightly more massive then its near twin planet uranus. The orbital period of planet neptune is 165 years. The distance between planet neptune and he sun is 4.495 billion km.The surface area of neptune is 7.618 billion km square and planet neptune length of day is 0 days 16 hours and 6 minute.

AGE OF NEPTUNE PLANET : Planet neptune is 4.503 billion year old. Planet neptune was also formed at the same time when other planet were formed in the solar system, from the large spinning disk of gas and dust. Astronomers think that all this was happen in the past 4.6 billion year before. So planet neptune is about 4.6 billion year old. if you want to know the age, temperature,size and etc of planet mars then click here to read full detail

COLOR OF PLANET NEPTUNE : Planet neptune is made up,of thick soup of water,ammonia, and methane above the solid center of the earth. Its atmosphere is made up of hydrogen, helium and methane. Methane gives neptune a blue color similar to planet uranus. Neptune has six rings, but they are difficult to see.

SIZE OF PLANET NEPTUNE : Planet neptune is nearly four times wider than planet earth, with a radius of 15,299.4 miles (24,622 kilometers). If the earth were the size of a nickle, neptune would have been as big as a baseball. At an average distance of 2.8 billion miles (4.5 billion kilometers),Neptune is 30 astronomical units from the sun.

TEMPERATURE OF PLANET NEPTUNE : Planet neptune has an average temperature of about minus 200 degree celcius (392 degrees fahrenheit). It is farthest known planet in the solar system, it is located about 30 times far from the sun than the earth.

WHY PLANET NEPTUNE IS IN BLUE COLOR : The atmosphere of planet neptune is made up of hydrogen, helium, and methane. In the above atmosphere of neptune, methane abosrbs red light from the sun but reflect blue light from the sun back in to space. This is why neptune look like or we can say it appears blue.

SPECIAL ABOUT PLANET NEPTUNE : 30 times as far away from the sun as the earth, planet Neptune is the only planet in our solar system that is not visibleto the naked eye and has been first predicted by methamatics before its discovery. In the year 2011, neptune finished or completed its first 165 year class since its discovery in 1846.

NASA RESEARCH ON PLANET NEPTUNE : NASA's voyager 2 is the only spacecraft that visited neptune in the year 1989 in the summer, and become the first spacecraft to observe the ultimate target of planet neptune. Passing approximately 4,950 kilometers (3,000 mi) from neptune' s north pole, in the year 1977 voyager 2 made its closest approach to any planet, 12 year after leaving earth. latest update from ISRO,phobos moon image found full detail click here to read full information.

PLANET NAPTUNE GRAVITY : The scientist had told that, the neptune is 3 times the size of the earth and 17 times the mass. however, due to the vastness of the gas, its density is 1.638 G/cm3. All of this works for s surface gravity of 11.15 m/s2 ( or 1.14g ), which is again measured in planet neptune's cloud top.

IS THERE OXYGEN ON PLANET NEPTUNE : Yes, planet neptune has lots of oxygen, but non of it is gaseous or in its atmosphere. the atmosphere of planet neptune is composed of hydrogen (80%), helium (19%) and methane (1%).

PLANET NEPTUNE MOONS : Planet neptune has 14 moons, which are, triton, thalassa naiad, neso, proteus, despina, galatea, halimede, laomedia, psamathe, larissa, nereid, hippocamp and sao.There are top 4 moon of planet neptune.

1: TRITON MOON : Triton moon is the largest natural satellite of the planet naptune. The triton moon is discovered in the year 1846 of october 10. The english astronomer (william lassel) discovered this moon. This moon is the first neptonian moon to be discovered. The rdius of this moon is 1,353.4 km, orbital period of this moon is 141 hours, gravity of this moon is 0.779 m/s2, surface area is 23018000 km2 and temperature of this moon is 38 K ( -235.2 degrees ceclius).

2: THALASSA MOON : The thalassa moon is also known as, neptune IV, this moon is the second innermost satellite of the planet neptune. Thalassa moon was named after sea goddess thalassa,daughter of aether and hemera from the greek mytholgy. The word thalassa is also known as sea in the greek language.It discoverd in the year 1989 on September 18, the radius is 41 km, the orbital period of this moon is 7 hour, the gravity on this moon is 0.015 m/s2.

3: NAIAD MOON : The naiad moon is also known as neptune III, this moon is the innermost satellite of planet neptune, it named after the naiad of greek legend. The radius of this moon is 33 km, this moon is discovered in the year 1989, on september 18, the gravity of this moon is 0.012 m/s2.

4: NEREID MOON : The nereid moon is also known as neptune II, this moon is the third largest moon of the planet neptune. In the comparison of all moons in the solar system, this moon has the most eccentric orbit. This moon was the second moon of the planet neptune to be discovered by kuiper in the year 1949.This moon has the orbital period of 360 day, it is discovered in the year 1949 on may 1st, the radius of this moon is 170 m and gravity of this moon is 0.071 m/s2.
