Question:

Is there a planet that is bigger than earth that is going to hit earth in a year and a half?

Answer:

I find nothing on a planet to hit Earth. However, the magnetic poles are set to shift in Oct 2012 which could cause trouble!!

Space

An overwhelming majority of fiction is set on or features the Earth. However, authors of speculative fiction novels and writers and directors of science fiction film deal with Earth quite differently from authors of conventional fiction. Unbound from the same ties that bind authors of traditional fiction to the Earth, they can either completely ignore the Earth or use it as but one of many settings in a more complicated universe, exploring a number of common themes through examining outsiders perceptions of and interactions with Earth.

Moon Planet
Colonization of Mars

The colonization of Mars refers to the concept of humans living on Mars. Originally a science-fiction idea it is now the subject of serious feasibility studies.

Astronomy
Planets in fiction

The Solar System and its various bodies (planets, asteroids, moons, etc.) were the earliest objects to be treated as fictional locations in works of science fiction. Among these, imaginary voyages to and explorations of Earth's Moon are found in seventeenth century literature. By the early twentieth century, following the increase in scientific and technological development spurred by the Industrial Revolution, fictional journeys to (or from) the Solar System's other planets had become common in fiction.

Early literature regarding the Solar System, following scientific speculations dating back to the 17th century, assumed that every planet hosted its own native life forms—often assumed to be human in form, if not in attitudes. Later literature began to accept that there were limits set by temperature, gravity, atmospheric pressure and composition, or the presence of liquids that would set bounds on the possibility of life as we know it existing on other planets. By the 19th century the Moon was given up as an airless desert, incapable of supporting life on its surface (hopes for subsurface life continued until later). Jupiter and the planets beyond were too large, too cold, and had atmospheres composed of poisonous chemicals. Mercury was too close to the Sun and its surface was exposed to extremes of temperature. The asteroids were too tiny and airless. By the early 20th century, prospects for life in the Solar System focused on Venus, the larger moons of Jupiter and Saturn, and especially Mars.


Planetary science

Planetary science (rarely planetology) is the scientific study of planets (including Earth), moons, and planetary systems, in particular those of the Solar System and the processes that form them. It studies objects ranging in size from micrometeoroids to gas giants, aiming to determine their composition, dynamics, formation, interrelations and history. It is a strongly interdisciplinary field, originally growing from astronomy and earth science, but which now incorporates many disciplines, including planetary astronomy, planetary geology (together with geochemistry and geophysics), atmospheric science, oceanography, hydrology, theoretical planetary science, glaciology, and the study of extrasolar planets. Allied disciplines include space physics, when concerned with the effects of the Sun on the bodies of the Solar System, and astrobiology.

There are interrelated observational and theoretical branches of planetary science. Observational research can involve a combination of space exploration, predominantly with robotic spacecraft missions using remote sensing, and comparative, experimental work in Earth-based laboratories. The theoretical component involves considerable computer simulation and mathematical modelling.

Environment

In journalism, a human interest story is a feature story that discusses a person or people in an emotional way. It presents people and their problems, concerns, or achievements in a way that brings about interest, sympathy or motivation in the reader or viewer.

Human interest stories may be "the story behind the story" about an event, organization, or otherwise faceless historical happening, such as about the life of an individual soldier during wartime, an interview with a survivor of a natural disaster, a random act of kindness or profile of someone known for a career achievement.
