What is a Planet? | Planets – NASA Solar System Exploration

Introduction. This seemingly simple question doesn''t have a simple answer. Everyone knows that Earth, Mars and Jupiter are planets. But both Pluto and Ceres were once considered planets until new discoveries triggered scientific debate about how to best describe them—a vigorous debate that continues to this day. The most recent definition of a planet was adopted by the

Timeline of discovery of Solar System planets and their moons

The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and

Solar System History 101

The smaller, inner planets are rocky, and at least one has life on it. The giant outer planets are shrouded in gas and ice; miniature solar systems in their own right that boast intricate rings and moons. Scattered throughout the solar system are small worlds like lumpy asteroids and comets and complex dwarf planets like Pluto and Ceres.

Formation and evolution of the Solar System

OverviewFormationHistorySubsequent evolutionMoonsFutureGalactic interactionChronology

The nebular hypothesis says that the Solar System formed from the gravitational collapse of a fragment of a giant molecular cloud, most likely at the edge of a Wolf-Rayet bubble. The cloud was about 20 parsecs (65 light years) across, while the fragments were roughly 1 parsec (three and a quarter light-years) across. The further collapse of the fragments led to the formation of dense cor

All About Mercury | NASA Space Place – NASA Science for Kids

Mercury is the smallest planet in our solar system. Mercury is a terrestrial planet. It is small and rocky. Mercury has a thin exosphere. Mercury''s surface can be as hot as 800 degrees F during the daytime and as cold as -300 degrees F during the nighttime. (But Mercury is not the hottest planet in the solar system. The hottest planet is Venus.)

Oldest Known Planet Identified

This planet''s tale also gives astronomers an idea of where planets may reside and how many could exist. The planet was born before many heavier elements existed in space, such as oxygen, carbon and silicon. It''s birth in such an element-poor globular cluster like M4 may imply that planets are more common in such environments than once thought.

The order and arrangement of the planets and other bodies in our solar system is due to the way the solar system formed. Nearest to the Sun, only rocky material could withstand the heat when the solar system was young. For this reason, the first four planets – Mercury, Venus, Earth, and Mars – are terrestrial planets.
