The inner planets

The Inner Planets

  • Mercury

  • Venus

  • Earth

  • Mars


Characteristics of the inner planets

Characteristics of the Inner Planets

  • They are 4 planets closest to the sun: Mercury, Venus, Earth and Mars. Located inside Asteroid Belt

  • Very similar to each other, they are small and have rocky surfaces. They are dense. Do NOT have rings

  • Often called “terrestrial planets” because they resemble Earth, “terra-” means “Earth”


Mercury

Mercury

  • Size- about 38% of Earth’s diameter

    it is 4878 km

  • Distance from sun- about 39% of Earth’s distance it is 58,000,000 km

  • Surface- thin, hard rocky surface covered with many plains and craters

  • Atmosphere- very thin


Mercury1

Mercury

  • Ability to support life- none, there is NOT any sign of life on Mercury, lack of water and oxygen along with hot temperatures make life unlikely

  • Moons- none

  • Rotation- 59 Earth days

  • Revolution- .24 Earth years

  • Daytime(sunlit side) temperature 430ºC Nighttime(shaded side) temperature

    -190ºC

Venus

Venus

  • Size- slightly smaller than Earth

    95% of Earth’s diameter, it is 12,104 km

  • Distance from sun- about 2/3 of Earth’s, it is 108,000,000 km from sun

  • Surface- covered with rock similar to some parts of Earth, has volcanoes with lava flows and strange domes


Venus1

Venus

  • Atmosphere- Very thick and cloudy, mostly carbon dioxide, clouds partly sulfuric acid. The thick atmosphere traps heat making it HOT!

  • Atmospheric pressure is 90 times heavier than Earth’s and would crush a human


Venus2

Venus

  • Atmosphere continued- Mostly carbon dioxide so greenhouse effect is strong

  • Has clouds of sulfuric acid

  • Ability to support life- Life does NOT appear to exist on Venus, lack of water along with harsh temperatures and atmosphere make life on Venus unlikely


Venus3

Venus

  • Sometimes called “Earth’s twin” or “Earth’s sister planet” due to similarity

  • Retrograde rotation- rotates “backward” from east to west (opposite of Earth)

  • Rotates very slowly, one rotation takes about 8 Earth months and one revolution around sun takes about 7.5 Earth months (One day is longer than one year)

  • Moons- None


Venus4

Venus

E a r t h

Earth

  • Size- 12,756 km diameter

  • Distance from Sun- 150,000,000 km

  • Surface- Crust is a solid rocky surface, 70% is covered by water

  • Atmosphere- up to 100 km thick, made up of 78% Nitrogen, 21% Oxygen, 1% other gases


E a r t h1

Earth

  • Ability to Support Life- Life does exist on Earth. Gaseous oxygen, liquid water and moderate temperatures are hospitable for life on Earth

  • Rotation takes 24 hours

  • Revolution takes 365.25 days

  • Earth has one moon

Mars

  • Size- 53% of Earth’s diameter, it is 6794 km

  • Distance from Sun- about 1.5 times distance of Earth

    It is 228,000,000 km from sun

  • Surface-Rocky surface with carbonite rocks high in iron, creating red color Polar ice caps contain frozen water and carbon dioxide


Do now

Mars

  • Atmosphere- Very thin, with thin clouds Mostly carbon dioxide

  • Ability to support life- It is possible that primitive bacteria may have lived on Mars or may now live there but none has been found. Existence of liquid water makes life on Mars a possibility


Do now

Mars

The dwarf planets

The Dwarf Planets

  • Pluto- was classified as a planet, now classified as a dwarf planet

  • Eris- new dwarf planet, past Pluto it is an icy body near the edge of our solar system. Say

Planets and dwarf planets compared

Planets and Dwarf Planets compared

  • Dwarf planets are smaller than planets

  • Both orbit the Sun

  • Both are large enough that their gravity pulls them into the shape of a sphere

  • Planets clear smaller objects out of their orbit. Dwarf planets can not because of their weaker gravity

Background info on dwarf planets

Background info on Dwarf Planets

  • There are currently three official dwarf planets. Pluto, formerly the smallest of the nine "traditional" planets, was demoted to dwarf planet status. Ceres, the largest asteroid in the main asteroid belt between Mars and Jupiter, was also declared a dwarf planet. The third and final (for now!) dwarf planet is Eris, an icy body on the edge of our Solar System that was discovered recently in 2005. Eris was temporarily labeled 2003 UB313 when it was first discovered, and given the nickname "Xena", before astronomers settled on the official name of Eris.

  • What's the difference between regular planets and dwarf planets? As you might guess, it's partly an issue of size, with dwarf planets being smaller. But just how big does a planet need to be to become a full-fledged planet instead of a dwarf? You might think the minimum size requirement is arbitrary, but the size cutoff is actually based on other properties of the object and its history in the Solar System. Both planets and dwarf planets orbit the Sun, not other planets (in which case we call them moons). Both must be large enough that their own gravity pulls them into the shapes of spheres; this rules out numerous smaller bodies like most asteroids, many of which have irregular shapes. Planets clear smaller objects out of their orbits by sucking the small bodies into themselves or flinging them out of orbit. Dwarf planets, with their weaker gravities, are unable to clear out their orbits.Though there are just three dwarf planets now, their number is expected to grow. Scientists estimate there may be 70 dwarf planets amongst outer solar system objects that have been discovered already. Since we don't know the actual sizes or shapes of many of the objects we've found (because they are so far away), we can't yet determine whether they are actually dwarf planets or not. More observations and better telescopes will help us determine which other objects are dwarf planets. Astronomers speculate that there may be 200 or so dwarf planets out through the distance of the Kuiper Belt, an icy band of frozen planetoids on the edge of our Solar System.
