X makes nine: a distant ice giant in the solar system
Science Progress
|July 26, 2017
Summary
Astronomers may have found evidence for a ninth planet in our solar system. This potential massive planet, located beyond Neptune, could explain unusual orbits of distant celestial bodies.
Area of Science:
- Astronomy and astrophysics
- Planetary science
Background:
- Our solar system currently has eight planets after Pluto's reclassification.
- The Kuiper Belt hosts numerous small celestial bodies with unusual orbital patterns.
Purpose of the Study:
- To investigate the potential existence of a ninth planet.
- To explain the observed clustering of Trans-Neptunian Objects (TNOs).
Main Methods:
- Utilizing computational simulations to model gravitational influences.
- Analyzing the orbital dynamics of small celestial bodies in the outer solar system.
Main Results:
- Postulated the existence of a large planet, approximately ten times Earth's mass.
- This hypothetical planet's orbit is hundreds of times farther from the Sun than Earth's.
Conclusions:
- The simulated presence of a ninth planet provides a plausible explanation for TNO orbital clustering.
- Direct observational evidence is pending, but future telescopes may confirm its existence.

01:18Kepler's Third Law of Planetary Motion
4.4K
In the early 17th century, German astronomer and mathematician Johannes Kepler postulated three laws for the motion of planets in the solar system. In 1909, he formulated his first two laws based on the observations of his forebears, Nikolaus Copernicus and Tycho Brahe. However, in 1918, he published his third law of planetary motion, which gives a precise mathematical relationship between a planet's average distance from the Sun and the amount of time it takes to revolve around the Sun. It...

Polish astronomer Nikolaus Copernicus put forth a theory that stated a heliocentric model for the solar system. According to this heliocentric theory, all the planets, including Earth, orbit the Sun in circular orbits.

01:29Kepler's Second Law of Planetary Motion
5.4K
In the early 17th century, German astronomer and mathematician Johannes Kepler postulated three laws for the motion of planets in the solar system. His first law states that all planets orbit the Sun in an elliptical orbit, with the Sun at one of the ellipse's foci. Therefore, the distance of a planet from the Sun varies throughout its revolution around the Sun.
While in an elliptical orbit, the total energy of the planet is conserved. Therefore, the planet slows down when it is at apogee and...

01:24Acceleration due to Gravity on Other Planets
5.0K
The gravitational acceleration of an object near the Earth's surface is called the acceleration due to gravity. It can be measured by conducting simple experiments on Earth. However, such an experiment is impossible to conduct on the surface of other planets.
Astronomical observations are thus used to measure the acceleration due to gravity on other planets. This can be determined by observing the effect of a planet's gravity on objects close to it. The crucial factor that helps in this...

No object with a finite mass can travel faster than the speed of light in a vacuum. This fact has an interesting consequence in the domain of extremely high gravitational fields.
The minimum speed required to launch a projectile from the surface of an object to which it is gravitationally bound so that it eventually escapes the object’s gravitational field is called the escape velocity. The escape velocity is independent of the mass of the object. Merging the idea of escape...
