radiation, i think
When two objects are touching and transfer heat, it is called conduction. Conduction is the transfer of heat energy through direct contact between particles of different temperatures.
The method of heat transfer that can take place between two objects at different temperatures placed without touching each other in a vacuum is radiation. Radiation is the transfer of heat energy through electromagnetic waves, which does not require a medium for propagation. Objects with higher temperatures emit infrared radiation that is absorbed by objects with lower temperatures, leading to an exchange of heat energy.
Heat transfer.

When objects of two different temperatures are in contact, heat transfer occurs. The hotter object will transfer heat to the cooler object until they reach thermal equilibrium, where their temperatures are the same. This process is governed by the laws of thermodynamics.

Conduction.
Thermal energy travels by conduction, convection, and radiation. Conduction occurs when two or more objects of different temperatures are touching each other. The heat flows from the warmer object to the cooler object, until the objects reach equal temperatures. Convection is the transfer of thermal energy through a moving liquid or gas. Radiation is the transfer of thermal energy though matter and space.
No, two objects do not have to be touching to transfer heat through conduction. Heat can also be transferred through conduction between objects that are in close proximity to each other.
Until the objects touching have equal temperatures.
Radiative heat transfer can occur between objects where there are no molecules. This type of heat transfer does not rely on the presence of a medium for energy transfer, as it involves the emission and absorption of electromagnetic radiation between objects at different temperatures.
