Parts-per-million chart of the relative mass distribution of the Solar System, each cubelet denoting 2 × 10 24 kg. This article includes a list of the most massive known objects of the Solar System and partial lists of smaller objects by observed mean radius.
Titan's dense atmosphere and low gravity mean that the flight power for a given mass is a factor of about 40 times lower than on Earth. [3] The atmosphere has 1.45 times the pressure and about four times the density of Earth's, and local gravity (13.8% of Earth's) make flight easier than on Earth, although cold temperatures, lower light levels ...
Enormous Lyα nebula (ELAN) Four quasars embedded in the nebula. Likely progenitor of a massive galaxy cluster at z=2.05. Fabulous Nebula [13] 969,000 ly (297,000 pc) [14] Enormous Lyα nebula (ELAN) Also called SDSS J1020+1040 nebula, after the central quasar (aka 4C 10.29), located at z=3.164. Inspiraling material.

Titan's abrupt demise was apparently caused by the same deep-sea forces that make expeditions like it so rare. It's why fewer people have been to Titanic ocean depths than have been to space.
The mean expansion velocity of the nebula seems to be slow at 20 km/s at the outer layer, [7] while it also reaches a maximum expansion velocity of 60 km/s relative to its central star. [8] Its central star has a magnitude of around 14m [7] and a temperature of around 47,000--59 000 K. [9] The most characteristic feature of IC 4997 is its ...

NGC 3132 (also known as the Eight-Burst Nebula, [2] the Southern Ring Nebula, [2] or Caldwell 74) is a bright and extensively studied planetary nebula in the constellation Vela. Its distance from Earth is estimated at 613 pc or 2,000 light-years .
