Suppose that you discovered a planet with 200 times the mass of Earth Is this planet more likely to be Terrestrial or Jovian?
A planet with 200 times the mass of Earth is more likely to be a Jovian planet rather than a Terrestrial planet. Jovian planets are typically composed of gases and liquids, while Terrestrial planets are rocky in composition like Earth. The high mass suggests a gas giant planet similar to Jupiter or Saturn.
Do the terrestrial planets have much smaller masses than the Jovian planets?
The cores of jovian planets are very similar to terrestrial ones. Jovian planets are simply a more evolved form of terrestrial planet contrary to popular perception. Jovian planets often have a lot of hydrogen, helium, methane, and/or volatile ices to make up its atmosphere to the point where oceans of these components cover the terrestrial core and billow the atmosphere to large proportions. Terrestrial planets absorbed less of these components from the leftover solar nebula leaving only the rocky surface and maybe some gas of an atmosphere.
Why is it more difficult for gases to escape from Jovian planets than terrestrial planets?
It is more difficult for gases to escape from Jovian planets because they have much stronger gravitational forces due to their larger mass, which means gases are held more tightly to the planet. Terrestrial planets have lower mass and weaker gravity, making it easier for gases to escape into space.
The difference between a jovian planet and a Terran planet?
Jovian Planets: Gas GiantsThe gas giants, popularly referred to as the Jovian planets, are the planets which are not composed of any solid matter. Technically speaking, the planets which have 10 times more mass than the Earth are classified as the Jovian planets. The examples of Jovian planets in our solar system, include the planet Jupiter, Saturn, Uranus and Neptune. These planets are referred to as the Jovian planets owing to their stark resemblance to the planet Jupiter, the largest planet in the solar system. Other than these four planets in our solar system, several other gas giants have been discovered in outer space.Terrestrial Planets: Inner PlanetsTerrestrial planets, also known as the rocky planets or the telluric planets, are those planets which are predominantly composed of silicate rocks. The examples of terrestrial planets in the solar system are Mercury, Venus, Earth and Mars. These planets resemble the planet Earth to a significant extent, and hence they are referred to as 'Earth-like' or 'terrestrial' (derived from the Latin word the Earth - terra). Other than the Earth, and three other terrestrial planets in our solar system, the scientists have identified a number of planets with terrestrial traits in outer space.Jovian Planets Vs Terrestrial PlanetsThat brings us back to the terrestrial planets vs Jovian planets comparison. The most basic difference between Jovian and terrestrial planets is their size. While the Jovian planets are gigantic, the terrestrial planets are considerably small. In fact, the smallest Jovian planet is 10 times larger than the planet Earth, which is the largest terrestrial planet. Even in terms of the mass, Jovian planets score over their terrestrial counterparts. The smallest Jovian planet has 15 times more mass than the Earth. The surface of the Jovian planets is made up of gases, while the surface of the terrestrial planets is made up of solid rock. Similarly, the atmosphere of the terrestrial planets is predominantly made up of nitrogen and carbon dioxide, while the atmosphere of the Jovian planets is made up of hydrogen and helium. As far as the distance from the Sun is concerned, the terrestrial planets are closer to the Sun, and hence are referred to as inner planets, while the Jovian planets are farther, and hence are referred to as the outer planets. Surprisingly, however, the speed at which the Jovian planets rotate is much faster than the terrestrial planets. The density of the terrestrial planets is five times that of water, while the density of the Jovian planets is as much as that of water. Yet another point of difference between the Jovian planets and the terrestrial planets is the number of natural satellites. While the terrestrial planets either have none or a very few (Mercury-0, Venus-0, Earth-1 and Mars-2), the Jovian planets have a large number of them.
The Jovian planets are more massive but less dense than the terrestrial planets?
Yes, that is correct. The Jovian planets are composed mainly of gases like hydrogen and helium, making them less dense overall compared to the terrestrial planets which have solid surfaces. Additionally, the Jovian planets have much larger volumes due to their gaseous compositions, leading to their greater mass.
Do Jovian planets rotate faster than Terrestrial planets?
Yes, Jovian planets rotate faster than terrestrial planets. For example, Jupiter completes a rotation in about 10 hours, while Earth takes roughly 24 hours. This difference is mainly due to the Jovian planets having a greater amount of mass and their composition, which affects their rotation speeds.
WHY is it that only jovian planets have ring?
Jovian planets have rings because their strong gravitational forces can capture and maintain orbiting particles and debris that form the rings. This is due to their larger size and mass compared to terrestrial planets. The rings around Jovian planets are made up of rock, ice, and dust particles that orbit around the planet in thin bands.
Which new idea has been added into your theory of solar system formation as a result of the discoveries extrasolar planets?
these are the multiple choice options:a. Jovian planets can migrate inward from the orbits in which they are born.b. In some star systems, it is possible for jovian planets to form in the inner solar system and terrestrial planets to form in the outer solar system.c. Some of the "exceptions to the rules" in our own solar system are likely to have been the result of giant impacts.d. In addition to the categories of terrestrial and jovian, there must be an "in-between" category of planet that has the mass of a jovian planet but the composition of a terrestrial planet.
How do the terrestrial planets differ from the Jovian planets?
The jovian planets have no solid ground just compressed gases the terrestrial planets have solid ground. The Jovian planets are named gas giants because they are farther then the sun and are not solid and the terrestrial planets are closer to the sun and do not have as much gases.
Why are the Jovian planets so much larger than the terrestrial planets?
Jovian planets are larger because they are primarily composed of gases such as hydrogen and helium, which are less dense than the rocky materials that make up terrestrial planets. This allows them to accumulate more mass and grow to much larger sizes. Additionally, their greater distance from the Sun allowed them to retain more of their original gaseous material during the formation of the solar system.
Why don't terrestrial planets have rings like the Jovian planets?
While the terrestrial planets are mostly rocky with metallic cores, the Jovian planets are huge balls of gas. The Jovian Planets are also much larger than the terrestrial ones.
Venus is most similar in size and mass to which planet?
Venus is most similar in size and mass to Earth. Both planets are considered terrestrial planets and have similar compositions and densities, which is why they are often referred to as "sister planets."
