Planets are there

Over the next 12 years, Lucy will fly by one main-belt asteroid and seven Trojan asteroids. JPL's lucky peanuts are an unofficial tradition at big mission events. A new paper details how the hydrological cycle of the now-dry lake at Jezero Crater is more complicated than originally thought. DART's mission is to determine if flying a spacecraft into a small solar system body could be a reliable technique to deflect an asteroid.

The spacecraft will continue collecting data about Mars, but engineers will stop sending commands until mid-October. Winds in the outermost "lane" of Jupiter's Great Red Spot are accelerating — a discovery made possible by Hubble. The dusty rocks of Jezero Crater are beginning to tell their story — thanks to the seven powerful science cameras aboard Perseverance. This year, the minimum extent of Arctic sea ice dropped to 1.

NASA's Lucy is set to launch in October on the first mission to study the Trojan asteroids — swarms of asteroids associated with Jupiter. Lucy Is Going to Space! The lander cleared enough dust from one solar panel to keep its seismometer on through the summer, allowing scientists to study three big quakes.

Futuristic electric thrusters emitting a cool blue glow will guide the Psyche spacecraft through deep space to a metal-rich asteroid. Perseverance successfully collected its first pair of rock samples, and scientists already are gaining new insights into the region. The rock core is now enclosed in an airtight titanium sample tube, and will be available for retrieval in the future. This is the order of the planets. The smallest planet in our Solar System is Mercury, which is only one third the size of Earth, while the biggest planet in the Solar System is Jupiter, which is 11 times bigger than our Earth, and more than 1, could fit inside it if it were hollow.

Mercury is only 0. The farthest planet, Neptune, is 30 AU or 4. Here is a table about the planets in our Solar System, their mass, size, and distance from the Sun. Many other planetary systems have either less, equal, or even more planets than our Solar System. One interesting fact about our Solar System is that it lacks a specific type of planet called a Super-Earth. Super-Earth planets are terrestrial planets that are more massive and much bigger than our Earth, by several times.

These giant planets are usually smaller than the gas giants; however, they should harbor life, and it would be interesting to think about how life would evolve on such a planet. Just imagine our Earth being four times bigger, at least, how many species could there have been in such a world. You could say that there are 13 planets in our Solar System, maybe even more. The dwarf planets Ceres , Haumea , Makemake , and Eris , are also orbiting our Sun, so there are actually 13 planets in our Solar System.

Some consider that the biggets moon of Pluto, named Charon, might also be a dwarf planet. Regardless of its classification, Charon is even bigger than Ceres.

Ceres is an attractive dwarf planet since it is also classified as an asteroid, the biggest yet discovered.
