How hot is the solar system

Is Mercury the hottest planet in the Solar System?

Despite being the closest planet to the Sun at a distance of 36-million miles (58-million kilometres), Mercury is not the hottest planet in the solar system. Mercury may be the closest planet to the Sun, but it does not have a significant atmosphere.

OverviewEtymologyGeneral characteristicsCompositionStructure and fusionMagnetic activityLife phasesLocation

The Sun is the star at the center of the Solar System. It is a massive, nearly perfect sphere of hot plasma, heated to incandescence by nuclear fusion reactions in its core, radiating the energy from its surface mainly as visible light and infrared radiation with 10% at ultraviolet energies. It is by far the most important source of energy for life on Earth. The Sun has been an object of veneration in many cultures. It has been a central subject for astronomical research since antiquity.

OverviewFormation and evolutionGeneral characteristicsSunInner Solar SystemOuter Solar SystemTrans-Neptunian regionMiscellaneous populations

The Solar System formed at least 4.568 billion years ago from the gravitational collapse of a region within a large molecular cloud. This initial cloud was likely several light-years across and probably birthed several stars. As is typical of molecular clouds, this one consisted mostly of hydrogen, with some helium, and small amounts of heavier elements fused by previous generations of stars.

Formation and evolution of the Solar System

The Solar System is chaotic over million- and billion-year timescales, [102] with the orbits of the planets open to long-term variations. Around 5.4 billion years from now, the core of the Sun will become hot enough to trigger hydrogen fusion in its surrounding shell. [118]

Do all planets have the same temperature?

In terms of temperature, no two planets have the same one since it is the result of various processes. Generally, a planet''s temperature is determined by two primary factors: its distance from the Sun and its atmosphere''s composition. What are the hottest and coldest planets in the solar system?

Our solar system includes the Sun, eight planets, five officially named dwarf planets, and hundreds of moons, and thousands of asteroids and comets. Our solar system is located in the Milky Way, a barred spiral galaxy with two major

Solar System History 101

Our solar system formed much later, about 4.6 billion years ago. It began as a gigantic cloud of dust and gas created by leftover supernova debris—the death of other stars created our own. Over the next 100,000 years, the cloud collapsed under its own gravity to form hot, dense protostars, one of which was our Sun. Our baby Sun kept

What is the average temperature on Earth?

The average surface temperature on Earth is 57 degrees Fahrenheit (14 degrees Celsius), which happens to be perfect for the existence and flourishment of life. Mars is the coldest of the inner rocky planets, and it orbits just outside the Sun''s habitable zone at an average distance of 142-million miles (228-million kilometres).

Jupiter

Jupiter is the largest planet in our solar system. If Jupiter was a hollow shell, 1,000 Earths could fit inside. Jupiter also is the oldest planet, forming from the dust and gases left over from the Sun''s formation 4.5 billion years ago. But it has the shortest day in the solar system, taking only 10.5 hours to spin around once on its axis.
