The Calabash Nebula, also known as the Rotten Egg Nebula or by its technical name OH 231.84 +4.22, is a protoplanetary nebula (PPN) 1.4 light years (13 Pm) long and located some 5,000 light years (47 Em) from Earth in the constellation Puppis.
Theoretical planetologists also use numerical models to understand how the Solar System planets were formed and develop in the future, their thermal evolution, their tectonics, how magnetic fields are formed in planetary interiors, how convection processes work in the cores and mantles of terrestrial planets and in the interiors of gas giants ...
The NPV, thus, plays a decisive dynamical role to stabilize hexagon jets. The influence of moist convection, which was recently suggested to be at the origin of Saturn's NPV system in the literature, is investigated in the framework of the barotropic rotating shallow water model and does not alter the conclusions.

Standish worked on the Jet Propulsion Laboratory Development Ephemeris.. Early versions refined the accuracy of these fundamental astronomical data-sets by including many recent and accurate observational data, new types of data, using improved data processing methods, including refined equations of motion which more accurately described the actual physics of the solar system.

The star and related planetary system are located 105 light years away, in the constellation Coma Berenices. Masses of all six of the planets in the system range from 3.9 M ⊕ (mass of Earth) to 8.5 M ⊕. All of the planetary orbits in the HD 110067 system are closer to their star than distance between the planet Mercury and the Sun. [3] [4]
PSR B1257+12, previously designated PSR 1257+12, alternatively designated PSR J1300+1240, [6] is a millisecond pulsar, 2,300 light-years (710 parsecs) from the Sun, in the constellation Virgo, rotating at about 161 times per second (faster than the blade of a blender). [1]
The nebular hypothesis is the most widely accepted model in the field of cosmogony to explain the formation and evolution of the Solar System (as well as other planetary systems). It suggests the Solar System is formed from gas and dust orbiting the Sun which clumped up together to form the planets.
Located on Ishtar Terra, the more northern of the planet's two major highlands, Maxwell Montes is 11 kilometres (36,000 ft) high. [1] It rises about 6.4 kilometers above and to the east (21,000 ft above, and 4 miles (6.44 km) to the east) of Lakshmi Planum, and is about 853 kilometres (530 mi) long by 700 kilometres (435 mi) wide.
