The total mass of the Jupiter Trojans is estimated at (0.30 ± 0.19) × 10–10 M Sun using all available physical characteristics of these asteroids. The mass of asteroids in the L4 swarm ((0.19 ± 0.11) × 10–10 M Sun) is higher than that in the L5 swarm ((0.11 ± 0.07) × ...
In our universe, this mass scale is roughly comparable to that of Jupiter. Significantly, since α≪1 in our universe, and we expect α≲1 more generally, planets supported by electromagnetic forces have smaller masses than their host stars. The mass scale of the cosmological horizon at the...
A Long㏄eriod Jupiter㎝ass Planet Orbiting the Nearby MDwarf GJ 849 1 We report precise Doppler measurements of GJ 849 (M3.5 V) that reveal the presence of a planet with a minimum mass of 0.82 M Jup in a 5.16 yr orbit. At a ... RP Butler,JA Johnson,GW Marcy,... - 《...
Discovery of 18 Jupiter mass RV companion orbiting the brown dwarf candidate ChaHa8 We report the discovery of a 16-20 Jupiter mass radial velocity companion around the very young (3 Myr) brown dwarf candidate ChaHa8. Based on high-resolution echelle spectra of ChaHa8 taken between 2000 and...
The mutual gravitational interactions can be quite complex, particularly in multisatellite systems. For example, the three innermost Galilean satellites of Jupiter (so named because they were discovered by Galileo in 1610)-Io, Europa, and Ganymede–are locked in a 4:2:1 mean-motion resonance with...
Orcus is named after the Roman God of Underworld like Pluto. Orcus was the punisher of broken oaths. Dwarf PlanetsThere are five other dwarf planets in the Solar System and all but one orbits in the Kuiper Belt. The odd one out is Ceres which orbits between Mars and Jupiter. ...
The locations of resonances are also indicated (vertical dotted lines), including the 3:1 mean-motion resonance with Jupiter and the 1:2 with Mars (M1:2), which deliver bodies to the NEO space. Diffusing orbits in the M1:2 resonance provide an independent constraint on the age of the ...
If a person weighs 500 N on Earth, what would she weigh on Jupiter, where the acceleration due to gravity is 26 m/s^2? What is the weight of a 3.0 kg object on the surface of the earth? A body of mass 20 kg is transferred from Earth to another p...
Felicia, the ballet dancer, has a mass of 45.0 kg. a.) What is Felicia's weight on Earth? b.) What is Felicia's mass o Jupiter, where the acceleration due to gravity is 25.0 m/s2? c.) What is Felic When you weigh yourself on good old terra fir...
Geographos is an Apollo that orbits the Sun in the asteroid belt that surrounds our star. The majority of the asteroids orbit between Mars and Jupiter.
