Actually, a glancing blow isn't possible. The gravitational pull between the two planets would be so great it would basically result in a head-on collision. Any life on those planets would have long since been extinguished prior to the collision due to the gravitational force. The planets themselves would be destroyed and all that would be left would be pieces of rubble.

I admit to having a couple problems with this answer. First, life would continue until the extinction, for if the bodies were moving towards a 'head on collision' the gravity would become such as to fragment either surface until - at worst - hours before impact. Second, there are two examples of glancing blows in our solar system that I am aware of: Mars and Earth. Most of Mars' northern surface is flat due to having become a sea of magma around four billion years ago. The object struck a glancing blow, but it was small and perhaps slow. It is believed that any ejecta remnants of the object all or mostly fell into Mars shortly after the strike. The Earth's moon was created by a similar strike, but in this case the object was much larger - although still relatively slow moving. Some of the object managed to leave the earth after striking it - along with significant portions of the Earth's atmosphere and crust. The molten ejecta eventually coalesced into the moon.
Now, I realize that in most instances either the object striking the planet (even if planet sized itself, as with the formation of the Earth's moon due to a Mars-sized body colliding with the Earth) would either meld with the planet (as with Mars' impact) or be reduced to a stream of molten slag that might later either form a moon or a ring of debris around the planet.
My question is - say, presuming the scenario in which the moon formed - if the object were moving faster and - due to orbital considerations and velocity - likely to only skim the surface of the planet - could it survive the impact. I realize that if no impact occurs, it is likely in this situation that one or both objects might be forced into a new orbit by the sling-shot situation (rather like some satellites sling shot around planets to increase their velocity and so reach the outer solar system). Could a sling shot, slowed by the friction of actual impacting / sliding along the surface - allow for the survival of both planets? I fully expect, even if survival occurs, that the surfaces of both will be reduced to magma oceans due to the cracking, crumpling, and tidal forces upon each of the crusts. But is it even theoretically possible?

No, the planets in our solar system rely on the Sun for light, energy, and gravity to maintain their orbits. If the Sun were to disappear, the planets would no longer have a source of heat and light, and they would eventually drift off into space in various directions.
There is a possibility that humans could survive and evolve on foreign planets with the right technology to support them. However, it would likely require significant advancements in fields such as biology, engineering, and sustainability to ensure long-term viability. It's a complex undertaking with many challenges to overcome.
It is a double or multiple star which could make planets less likely to be surrounding it.
Bu no
When the sun dies, it will expand into a red giant, engulfing the inner planets, including Earth. It is currently not known if human life could survive this scenario. In the far future, humanity may need to find new planetary systems to inhabit.
Example sentence - If she were careful, she could glance in his direction without him noticing her.
Nothing that we know of can survive the heat generated on surface of stars, therefore, no. Planets could carry life forms.
They could swerve into somebody's car and cause a collision

The outer planets are gas planets
could we grow plants on other planets? Answers please.
Could chameleons survive in the ocean why or why not???
A collision could occur when the distance between two vessels decreases and the bearing remains constant. This indicates that the vessels are on a collision course. Vigilance and timely action to change course or speed are critical to avoid a collision.
Could We Survive was created on 2008-03-18.
A collision could occur when the distance between two objects decreases and their bearings converge, meaning they are moving towards each other. This situation increases the risk of a collision because the objects are on a potential collision course due to their decreasing distance and converging paths.
Cattle from the East could not survive on the tough prairie grasses, but the could easily survive the harsh climate of the plains.
