Scientific notation is used to show numbers raised to powers of ten. Pluto is a planet. Therefore, Pluto cannot be put into scientific notation because there are no numbers in Pluto to put to a power of ten...
Planet Mars has a mass of 639 x 1021 kilograms (639,000,000,000,000,000,000,000kg)
I can't tell if you're referring to the planet or the element. The radius of the planet is about 1.516 x 10^3 miles.
It is a difference of scale. Interplanetary means between planets; it takes a ray of light minutes or hours to go from a planet to another planet. Intergalactic means between galaxies; it takes a ray of light hundreds of thousands of years, or even millions of years, to travel that distance.

The average distance from Earth to the planet Earth is approximately 0 miles, or 0 x 10^0 miles in scientific notation. This is because Earth is the reference point when measuring distances in space.

When? Mars and Earth are constantly moving, so the distance between them is constantly changing. If you're really interested, it would be trivial to look up their relative distances from the sun, and figure out how far apart they can ever be (if they're both on opposite sides of the sun) or how close they can ever get (if they're both on the same side of the sun). I'm not going to do that for you, though, because I would hate to spoil your joy of discovery.

Speed = Distance /Time = 1.98*1011 / 8*103 = 0.2475*108 = 2.475*107 km per hour.
Yes, the square of the orbital period of a planet is proportional to the cube of the average distance of the planet from the Sun. This relationship is known as Kepler's Third Law of Planetary Motion. It describes the mathematical relationship between a planet's orbital period and its average distance from the Sun.
Based on their average distance from the sun, the Earth is the nearest.
The average distance from the sun to Earth, our home planet
The period of revolution of a planet is most closely related to its distance from the sun. The further a planet is from the sun, the longer it takes to complete one revolution.
The average distance from the sun to Earth, our home planet
The average distance from the sun to a planet is its semi-major axis, which is the longest radius of its elliptical orbit.
The distance of planet X from the sun can vary depending on its orbit. An astronomical unit (AU) is the average distance between the Earth and the Sun, about 93 million miles. If you know the specific distance of planet X from the sun, you can convert it to astronomical units by dividing by the average distance of 1 AU.
