Ceres Was the First Asteroid to Be Discovered

Ceres Was the First Asteroid to Be Discovered

Ceres is considered as the first asteroid that was discovered in 1801. It is sometimes assumed that Ceres has been reclassified as a dwarf planet, and that it is therefore no longer considered an asteroid. For example, a news update at Space.com spoke of “Pallas, the largest asteroid, and Ceres, the dwarf planet formerly classified as an asteroid”, whereas an IAU question-and-answer posting states, “Ceres is the largest asteroid”. So, according at the point of view of Space.com Ceres is a dwarf planet that is considered as the smallest and closest one.

5 Dwarf Planets in our Solar System

5 Dwarf Planets In Our Solar System

Dwarf planets in our Solar System are Pluto, Eris, Haumea, Makemake and Ceres. It is estimated that there are more than 200 dwarf planets in the Kuiper belt of the outer Solar System and possibly more than 10,000 in the region beyond. A dwarf planet is a planetary-mass object that is neither a planet nor a natural satellite. It is a body orbiting the Sun that is big enough to round itself by its own gravity, but has not cleared its orbital path of other rival bodies. So let’s discover which ones are 5 dwarf planets in our solar system.

Top 10 Facts about Eris Dwarf Planet

Top 10 Facts about Eris Dwarf Planet

Eris dwarf planet is the most massive and second-largest dwarf planet in the known Solar System. Eris was discovered on October 21, 2003 by M.E. Brown, C.A. Trujillo, and D. Rabinowitz at the Palomar Observatory. It is named for the ancient Greek goddess of discord and strife. The name fits since Eris remains at the center of a scientific debate about the definition of a planet. As stated NASA “Eris first appeared to be larger than Pluto. This triggered a debate in the scientific community that led to the International Astronomical Union’s decision in 2006 to clarify the definition of a planet.

Top 10 Habitable Exoplanets

Top 10 Potentially Habitable Exoplanets

An exoplanet or extrasolar planet is a planet outside our solar system that orbits a star. This is a list of habitable exoplanets and possible exoplanets. We are introducing you top 10 potentially habitable exoplanets, that is based on estimates of habitability by the habitable exoplanets catalog (HEC), and data from the NASA Exoplanet Archive. The HEC is maintained by the Planetary Habitability Laboratory at the University of Puerto Rico at Arecibo.

Why Pluto is no longer a planet

Why is Pluto No Longer Considered a Planet?

Pluto was first discovered in 1930 by Clyde W. Tombaugh. Astronomers had always been thought that there would be a ninth planet in our Solar System, which was called planet X. After a year of observations, Tombaugh finally discovered an object in the right orbit, and declared that he had discovered Planet X. They named it Pluto. The name of the Pluto (the Roman god of the underworld) was suggested 11 years old girl. But in 2006 it is declared that Pluto is no longer a Planet. On February 17, 2018 the Washington Post wrote, that six years old Irish girl wrote to a NASA asking for Pluto’s return to the solar system planetary club.

Bright Lights on Dwarf Planet Ceres

The Mystery of Bright Lights on Dwarf Planet Ceres

Bright Lights on Dwarf Planet Ceres, pictured by NASA’s Dawn space probe. Ceres is the largest object in the asteroid belt, which lies between Mars and Jupiter. The diameter of dwarf planet Ceres is about 950 kilometers. Images taken nearly 46,000 kilometres from Ceres show that a bright spot on the planet, which scientists discovered previously, appears next to another slightly darker spot, NASA said in a news release. Scientists expect to receive better views of the mystery lights as the spacecraft closes in and spirals nearer the dwarf planet Ceres on March 6.

60 billion alien planets in a manned space of red dwarfs

Published the new research, allowing to calculate influence of clouds on climate of alien planets, rotating round red dwarfs. Conclusions of participants of the joint group of the Chicago and Northwest universities are based on exact computer modeling of behavior of clouds in the atmosphere of alien planets. But besides purely scientific interest, this research also allows to draw a conclusion that existence of a cloudy cover twice expands a manned space of red dwarfs. And it means that only in one galaxy in a manned zone of the stars there can be over 60 billion alien planets. The formula for calculation of a manned space of alien planets is places where they can keep liquid water on the surface. But it is insufficiently exact as almost doesn’t consider existence of clouds in the atmosphere of exoplanet.

Dawn Gets 40 Extra Days Time to Explore Vesta

NASA’s Dawn mission has received official confirmation that 40 extra days have been added to its exploration of the giant asteroid Vesta, the second most massive object in the main asteroid belt. The mission extension allows Dawn to continue its scientific observations at asteroid Vesta until August 26, while still arriving at the dwarf planet Ceres at the same originally scheduled target date in February 2015.

Star HD 10180 May Harbor Record Number of Planets

A sun-like star some 127 light years away may harbor a record number of planets, nine, spotted in another solar system. Our own solar system only possesses eight planets, with the recent demotion of Pluto to dwarf planet status by astronomers. Accepted for publication by the journal Astronomy and Astrophysics, the report by astronomer Mikko Tuomi of the United Kingdom’s University of Hertfordshire, looks at HD 10180, an often-examined star in the constellation of Hydrus, the water snake.
