7.1 Overview of Our Planetary System

We have even discovered other places in our solar system that might be able to support some kind of life. Figure 7.2 Astronauts on the Moon. The lunar lander and surface rover from the Apollo 15 mission are seen in this view of the one place beyond Earth that has been explored directly by humans. (credit: modification of work by David R. Scott

Exoplanets

Overview Most of the exoplanets discovered so far are in a relatively small region of our galaxy, the Milky Way. ("Small" meaning within thousands of light-years of our solar system; one light-year equals 5.88 trillion miles, or 9.46 trillion kilometers.) Even the closest known exoplanet to Earth, Proxima Centauri b, is still about 4 light-years []

Hypothetical Planet X

Pluto was considered the ninth major planet in our solar system until the definition of "planet" was changed by the International Astronomical Union (IAU) in 2016. This new definition reclassified Pluto as a dwarf planet. Even before the IAU action, back when it was discovered, it was thought that Pluto was as massive as Earth.

Solar system

Solar system - Origin, Planets, Formation: As the amount of data on the planets, moons, comets, and asteroids has grown, so too have the problems faced by astronomers in forming theories of the origin of the solar system. In the ancient world, theories of the origin of Earth and the objects seen in the sky were certainly much less constrained by fact. Indeed, a

Astronomers Stunned by Unexpected Discovery of New Celestial

New Horizons mission Principal Investigator Dr. Alan Stern says, "This is a groundbreaking discovery revealing something unexpected, new, and exciting in the distant reaches of the Solar System; this discovery probably would not have been possible without the world-class capabilities of Subaru Telescope."

In Depth | Our Solar System – NASA Solar System Exploration

Introduction. The planetary system we call home is located in an outer spiral arm of the Milky Way galaxy. Our solar system consists of our star, the Sun, and everything bound to it by gravity – the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune; dwarf planets such as Pluto; dozens of moons; and millions of asteroids, comets, and meteoroids.

Solar System

While astronomers have discovered thousands of other worlds orbiting distant stars, our best knowledge about planets, moons, and life comes from one place. The Solar System provides the only known example of a habitable planet, the only star we can observe close-up, and the only worlds we can visit with space probes. Solar System research is essential for understanding

Solar System Facts

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.

6 FAQs about [Discovery solar system]

What is NASA Discovery?

When it began in 1992, the program represented a breakthrough in the way NASA explores space. Discovery invites scientists and engineers to assemble a team to design exciting, focused planetary science missions that deepen what we know about the solar system and our place in it.

How did telescopic observations contribute to the discovery of planets?

Telescopic observations resulted in the discovery of moons and rings around planets, and new planets, comets and the asteroids; the recognition of planets as other worlds, of Earth as another planet, and stars as other suns; the identification of the Solar System as an entity in itself, and the determination of the distances to some nearby stars.

Which spacecraft led NASA's Exploration of the outer Solar System?

Two series of spacecraft led the way in NASA’s exploration of the outer solar system: Pioneer and Voyager. Although there were Pioneer flights to the Sun and Venus, the best known were Pioneer 10 and 11, which made NASA’s first visits to Saturn and Jupiter in 1973.

What is the Solar Dynamics Observatory?

The Solar Dynamics Observatory seeks to understand the Sun as a star and its influence on Earth and near-Earth space by observing the solar atmosphere in many wavelengths simultaneously. The mission studies what creates solar activity that causes various space weather effects.

Who invented the Solar System?

Around 1704, the term "Solar System" first appeared in English. [ 19 ] English astronomer and mathematician Isaac Newton, incidentally building on recent scientific inquiries into the speed at which objects fall, was inspired by claims by rival Robert Hooke of a proof of Kepler's laws.

When did we learn about the Solar System?

A clear distinction was not made until around the mid-17th century. Since then, incremental knowledge has been gained not only about the Solar System, but also about outer space and its deep-sky objects. The composition of stars and planets was investigated with spectroscopy.
